Are factors of 70 odd or even? - Answers

What is a factor? It is a whole number that divides another without any remainder.So what are the factors of 70?1 x 70 = 702 x 35 = 705 x 14 = 707 x 10 = 7010 x 7 = 7014 x 5 = 7035 x 2 = 7070 x 1 = 70so the factors of 70 are 1, 2, 5, 7, 10, 14, 35, 70So the factors themselves are both even (2, 10, 14, 70) and odd. (1, 5, 7, 35)..However, the number of factors is even (there are 8 of them).The number of factors for all numbers will be even exceptfor those numbers which are perfect squares, when it will be odd, eg 36:1 x 36 = 362 x 18 = 363 x 12 = 364 x 9 = 366 x 6 = 369 x 4 = 3612 x 3 = 3618 x 2 = 3636 x 1 = 36So the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 - nine of them.
