Best Answer

Take any two coprime numbers p and q. There are infinitely many such pairs.

Then the GCF of 9p and 9q will be 9.

For example, 9 = 120 and q = 121 gives

1080 and 1089

What two numbers have a GCF of 9 and LCM of 54?

To find two numbers with a greatest common factor (GCF) of 9 and a least common multiple (LCM) of 54, we can use the relationship between GCF, LCM, and the product of two numbers. The product of two numbers is equal to the product of their GCF and LCM. So, if GCF is 9 and LCM is 54, the product of the two numbers is 9 * 54 = 486. To find the two numbers, we need to find a pair of factors whose product is 486 and whose GCF is 9. The numbers that meet these criteria are 27 and 18.
