The GCF of 4 and 10 is 2.
50
The GCF is 1.
The GCF is 4.
The GCF is 4.
The GCF is 2.
The GCF of 8, 40, and 60 is 4.
The greatest common factor of 4, 6, 10, and 22 is 2.
Since 4 and 5 are coprime, GCF(4, 12, 10, 5) = GCF(4,5) = 1
The GCF of 5 and 10 is 5. The GCF of 4 and 12 is 4.
Well, to get a negative number, when multiplying, you must have a negative and a posative. Therefore their would be one negative and posative solution, which would allow you to find a GCF for both a posative and negative number. Here's and example: Find the GCF of 4, and -12 You would factor each of them : you would have 4: 2,2 1,4 -12: 6,-2 2,-6 12,-1 .12,1 3,-4 4,-3 You would then determine that using that data, 4 would be the greatest common facotr of those two numbers.
The GCF is 2.
