Question

Find the GCF of 29 and 18

Answer 1

1

Explanation:

29 is a prime number. Hence, the GCM of a number x and 29 is 1 if x isn't divisible by 29. Because 18 isn't divisble by 29, the GCM of 18 and 29 is 1.

Hopefully this answer helps you :)

Answer 2

1

Explanation:

The greatest common factor of two numbers is the largest number that both can divide into.

29 is a prime number. This means that it is only divisible by 1 and itself.

18 has the factors 1,2,3,6,9,18.

Only the number 1 is a shared factor between the two numbers, therefore 1 is the greatest common factor of 29 and 18.
