Answer: 4

16 = 2 x 2 x 2 x 2

36 = 2 x 2 x 3 x 3

There are two 2's in each factorization, so the GCF is 2 x 2 = 4

Q: What is the greatest common factor of 16 and 36 show work?

The factors of 15 are:1, 3, 5, 15The factors of 305 are:1, 5, 61, 305The GCF is 5.

Short answer: 2 Explanation: Let's factor out the smallest number first. The factors of 12 are 1,2,3,4,6, and 12. Now we'll take the largest of those factors and see if its a factor of the other two. 12 isn't a factor of either, so we'll look at the next biggest and work our way down. 6 is a factor of 18 but not 44 so that's out. 4 isn't a factor of 18. 3 isn't a factor of 44. 2 is a factor of both 18 and 44, so that is our greatest common factor.

The concept of common factors does not work with fractions because, once the domain is the rationals rather than integers, any rational can divide into any other rational. So any number can be a common factor and, therefore, there cannot be a greatest one. For example, consider 1000. 25/1000 = 0.025 1.50/1000 = 0.00150 75/1000 = 0.075 3.00/1000 = 0.00300 Thuse, 1000 can be considered a common factor. But by the same argument, so can 1,000,000; a billion, a googol.

To find the common factor when factorising, look for any common factors that can be divided evenly from all the terms in the expression. Divide each term by this common factor, and then factorise the resulting expression further if possible. This will help simplify the expression and make it easier to work with.

The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54The factors of 108 are: 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108The common factors are: 1, 2, 3, 6, 9, 18, 27, 54The Greatest Common Factor (GCF) is: 54
