by finding the half of the number and list the factors all the way to that number
The same way as finding factors of positive numbers but the answer includes both the positive and negative factors.
All of them. Different numbers have different numbers of factors.
List all the factors both numbers have and find the one with the most value
Decimals don't have factors.
By finding their common prime numbers.
Factors are whole numbers that will divide into other whole numbers leaving no remainders
Factors are used with whole numbers, not decimals.
Factors refer to whole numbers, not decimals.

You do a factor tree80/ \2 40/ \4 10/ \ / \2 2 2 5Circle all prime numbers (bold) and then list different combinations of those to find them. Like 2 x 2, 2 x 5 and then go on to 2 x 2 x 2, 2 x 2 x 5 etc. and those answers will each be a factor. 2 x 2 = 4, therefore 4 is a factor of 80.
Composite numbers have more than two factors whereas prime numbers have only two factors.
Decimals don't have factors.
Prime numbers have only two factors.
