The GCF is 3.
2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
This is an impossible set of numbers. If the LCM was 36, and the GCF was 3, then the numbers would be 6X6.
The GCF of 9 and 21 is 3.
You need at least two numbers to find a GCF. If that's 21, 24 and 27, the GCF is 3.
The GCF is 1.
The GCF is 3.
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.
2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
The GCF is 3.
The GCF is 3.
In math the GCF of the numbers 3 and 63 is three. In mathematics the GCF is the greatest common factor of two or more numbers. The GCF can be found by listing the prime numbers for each number and then multiplying the common prime numbers.
The GCF is 3.
The GCF of 39 and 126 is 3.
This is an impossible set of numbers. If the LCM was 36, and the GCF was 3, then the numbers would be 6X6.
The GCF of 9 and 21 is 3.
You need at least two numbers to find a GCF.
