A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 169 are 1, 13, and 169. The factors of 14365 are 1, 5, 13, 17, 65, 85, 169, 221, 845, 1105, 2873, and 14365. The common factors are 1, 13, and 169. This would mean that the greatest common factor is 169.
Least common multiple of 65 and 85 is 1105.
You need at least two numbers to find a GCF.
