How many factors does 71 have?

Answer 1

The only way you can really do these problems is to setup a table from one to seventy, and find a number that multiplies to give you 70. Once the numbers repeat, you have found all the factors.

1 x 70 = 70

2 x 35 = 70

5 x 14 = 70

7 x 10 = 70

10 x 7 = 70 (the numbers have now repeated, so we know we can stop)

The factors are:

1, 2, 5, 7, 10, 14, 35, and 70

So there are 8 factors.

Answer 2

71 is a Prime number so it only has two factors: 1 and itself.

Answer 4

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72.
