9 & 24
Pick any two coprime numbers. Multiply both by 9. Their GCF will be 9.
4 and 9 have a GCF of 1
The same as what? The GCF of two numbers will be the same; the GCF of 3 and 9 will always be 3. The GCF of 9 and 12 will also always be 3, but the GCF of 4 and 12 will always be 4.
You need at least two numbers to find a GCF. If that's 4 and 9, the GCF is 1.
You need at least two numbers to find a GCF. If that's 11 and 9, the GCF is 1.

The Greatest Common Factor of the two numbers is 9. 288/9 = 32, 405/9 = 45.
Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9. Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9. Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9. Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9.
You need at least two numbers to find a GCF. If that's 2 and 79, the GCF is 1. If that's 27 and 9, the GCF is 9.
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.
You need at least two numbers to find a GCF. If that's 18 and 9, the GCF is 9.
