Question

find out the common factors by process ​

Answer 1

Answer:

1) The GCF of 25 and 35 is 5

2)Greatest common factor (GCF) of 9 and 18 is 9. We will now calculate the prime factors of 9 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 18

3) The factors of 11 are 1 and 11. The factors of 17 are 1 and 17. So, the Greatest Common Factor for these numbers is 1 because it divides all them without a remainder.

4) Thus, the common factors of 16 and 12 are: 1, 2, and 4. Often in math problems, it can be desirable to find the greatest common factor of some given numbers. In this case, the greatest common factor is 4.

5)The numbers 20 and 30 have the factors 2 and 5 in common. Next, multiply the common factors to find the GCF. If there is only one common factor, there is no need to multiply. The GCF of 20 and 30 is 10.

6) Greatest common factor (GCF) of 77 and 88 is 11.
