4 and 9 have a GCF of 1

Any two coprime numbers

The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.

If the GCF of two composite numbers is 1, they are co-prime or relatively prime.

25 and 32

sometimes

No. Two composite numbers, like 4 and 9, can have a GCF of 1. They are said to be relatively prime or co-prime.

3 and 7?

The GCF of two prime numbers is 1.

25 and 36

4 and 9 hope it helps!! : )

No.

If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.

25, 49 and 121

Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.

Consecutive numbers have a GCF of 1.

The GCF of two or more prime numbers is 1 as for example the GCF of 19 and 23 is 1

Even composite numbers can, odd composite numbers can't.

Prime and relatively prime numbers all have a GCF of 1.

They are all composite numbers whose GCF is 1

Prime numbers have two factors, composite numbers have more than two.

Prime numbers have two factors, composite numbers have more than two.

Any consecutive composite integers, like 34 and 35.

Yes, of course. In fact the product of any two numbers is composite unless one of them is 1.
