The factors that 24 and 14 have in common are 1 and 2 only.
Start by factoring each of the numbers. 7=7 12=2x2x3 14=2x7 Remove the duplicated factors. 7 is duplicated between 7 and 14; so remove one 7. 2 is duplicated between 12 and 14; so remove one 2. Multiply together the remaining factors. 7x2x2x3=84 Answer: 84
Common factors are any numbers that are factors of each. The greatest common factor therefore is the largest number that appears in both lists. Factors of 52 1, 2, 4, 13, 26, 52 Factors of 84 1, 2, 3, 4, 6, 7, 12, 14, 28, 42, 84 Common factors would be - 4, 2, and 1 Therefore the greatest common factor is 4.
