Finding Factors Using Division Method

The division method finds the numbers that fully divide the given number. steps are given below:

Step 1: Since every number is divisible by 1, 1 will always be a factor.  Example: 75÷1 = 75


Step 2: Move to the next integer. Both divisor and quotient are the factors.

Prime Factors and Prime Factorization

Multiplying prime numbers to get the given number as their product is called prime factors. Prime factorization is breaking down the number into its prime factors.
Prime Factors of 75: Number 75 has only one prime factor.


Prime factors of 75: 3, 5

To find the prime factors of 75, divide 75 with the prime numbers 3 and 5.

Step 1: Divide 75 with the prime number 3

75÷3 = 25

Step 2: Divide 25 with the prime number 5

25÷5 = 5


5÷5 = 1
