What are all the factors, the prime factorization, and factor pairs of 78990?

Factors are the numbers you multiply together to get another number. For example, the factors of 15 are 3 and 5 because 3 × 5 = 15.

The factors of a number can be positive or negative, but they cannot be zero.

The factors of a number can be used to find out if the number is prime or not.

A prime number is a number that has only two factors: itself and 1. For example, the number 7 is prime because its only factors are 7 and 1.

To calculate the factors of 78990 , you can use the division method.

   1. Begin by dividing 78990 by the smallest possible number, which is 2.

   2. If the division is even, then 2 is a factor of 78990.

   3. Continue dividing 78990 by larger numbers until you find an odd number that does not divide evenly into 78990 .

   4. The numbers that divide evenly into 78990 are the factors of 78990 .

Now let us find how to calculate all the factors of Seventy-eight thousand nine hundred ninety :

    78990 ÷ 1 = 78990
    78990 ÷ 2 = 39495
    78990 ÷ 3 = 26330
    78990 ÷ 5 = 15798
    78990 ÷ 6 = 13165
    78990 ÷ 10 = 7899
    78990 ÷ 15 = 5266
    78990 ÷ 30 = 2633
    78990 ÷ 2633 = 30
    78990 ÷ 5266 = 15
    78990 ÷ 7899 = 10
    78990 ÷ 13165 = 6
    78990 ÷ 15798 = 5
    78990 ÷ 26330 = 3
    78990 ÷ 39495 = 2
    78990 ÷ 78990 = 1

As you can see, the factors of 78990 are 1 , 2 , 3 , 5 , 6 , 10 , 15 , 30 , 2633 , 5266 , 7899 , 13165 , 15798 , 26330 , 39495 and 78990 .

The factors of 78990 are the numbers that can evenly divide 78990 . These numbers are 1 , 2 , 3 , 5 , 6 , 10 , 15 , 30 , 2633 , 5266 , 7899 , 13165 , 15798 , 26330 , 39495 and 78990.

Thus, there are a total of 16 factors of 78990

Factor Pairs of 78990 are combinations of two factors that when multiplied together equal 78990. There are many ways to calculate the factor pairs of 78990 .

One easy way is to list out the factors of 78990 :
   1 , 2 , 3 , 5 , 6 , 10 , 15 , 30 , 2633 , 5266 , 7899 , 13165 , 15798 , 26330 , 39495 , 78990

Then, pair up the factors:
   (1,78990),(2,39495),(3,26330),(5,15798),(6,13165),(10,7899),(15,5266) and (30,2633) These are the factor pairs of 78990 .

There are a few different methods that can be used to calculate the prime factorization of a number. Two of the most common methods are listed below.

1) Use a factor tree :

   1. Take the number you want to find the prime factorization of and write it at the top of the page

   2. Find the smallest number that goes into the number you are finding the prime factorization of evenly and write it next to the number you are finding the prime factorization of

   3. Draw a line under the number you just wrote and the number you are finding the prime factorization of

   4. Repeat step 2 with the number you just wrote until that number can no longer be divided evenly

   5. The numbers written on the lines will be the prime factors of the number you started with

For example, to calculate the prime factorization of 78990 using a factor tree, we would start by writing 78990 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 78990 would be 2 x 3 x 5 x 2633.

2) Use a factorization method :

There are a few different factorization methods that can be used to calculate the prime factorization of a number.

One common method is to start by dividing the number by the smallest prime number that will divide evenly into it.

Then, continue dividing the number by successively larger prime numbers until the number has been fully factorised.

For example, to calculate the prime factorization of 78990 using this method, we keep dividing until it gives a non-zero remainder.

    78990 ÷ 2 = 39495
    39495 ÷ 3 = 13165
    13165 ÷ 5 = 2633
    2633 ÷ 2633 = 1

So the prime factors of 78990 are 2 x 3 x 5 x 2633.
