Identify the two numbers less than 20 with most factors

12 and 18 are two number less than 20 with most factor.

Step-by-step explanation:

We need to find a number less than 20 with most factor.

Factor: Split a number into small number with their multiple.

So, we find the factor of all the number less than 20.

1 = 1

2 = 2 x 1

3= 3 x 1

4= 1 x 2 x 4

5= 1 x 5

6=1 x 2 x 3 x 6

7=1 x 7

8=1 x 2 x 4 x 8

9=1 x 3 x 9

10=1 x 2 x 5 x 10

11=1 x 11

12=1 x 2 x 3 x 4 x 6 x 12

13=1 x 13

14=1 x 2 x 7 x 14

15=1 x 3 x 5 x 15

16=1 x 2 x 4 x 8 x 16

17=1 x 17

18=1 x 2 x 3 x 6 x 9 x 18

19=1 x 19

We can factors of 12 and 18 are 6.

Thus, 12 and 18 are two number less than 20 with most factor.
