If the GCF of two numbers p and q is 7, then the GCF of p2 and q2 is 14.
Prime and relatively prime numbers all have a GCF of 1.
You need at least two numbers to find a GCF.
4 and 120
There are infinitely many pair of numbers. Take any two numbers that are coprime. Double both of them. Their GCF is 2.
The GCF of two prime numbers is 1.
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.
To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
Two numbers have a GCF. Two sets of two numbers may have the same GCF.
You need at least two numbers to find a GCF.
Consecutive numbers have a GCF of 1.
No; two numbers can have only 1 GCF.
The GCF of two even numbers is even.
23 and 46 have a GCF of 23.
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
You need at least two numbers to find a GCF.
You don't; you need at least two numbers to find a GCF.
