You can do a T-chart and list out all the common factors then find the highest one or you can do upside down divisionwich is like this:Tle long division sighn upside down then the numbers that you are given on the inside then the numbers that go into all of them on the outside. keep doing this until all the numbers have nothing in common. Then multiply all the outside numbers and that is your answer

Give me the GCF numbers?
I'll exchange them for the numbers you want to know the GCF of.
What are all the gcfs for 15 and 27?
The factors of 15 are: 1, 3, 5, 15The factors of 27 are: 1, 3, 9, 27The common factors are: 1, 3The Greatest Common Factor (GCF) is: 3
What are the GCF's 50?
There are no GCFs of one number, but I'm sure you just mean factors. So, the factors are: 1, 2, 5, 10, 25, 50 (Technically, 1 is not a factor, and neither is 50, because factors of a number are any number that goes into it other than 1, and their-selves, but i thought I'd include them anyways)
How do you find gcf of negative number?
By treating it as a positive number. Since negative numbers include the factors of their positive counterparts and all positive numbers are greater than all negative numbers, the GCF will always be positive. The GCFs of (3, 9), (3, -9), (-3, 9) and (-3, -9) are all the same: positive 3.
