How to find factors of 20 by Division Method?
To find the factors of 20 by division method, we need the find the all numbers between 1 to 20, which divide 20 with 0 remainder, then the number is factor of 20.
Pair factors of 20
- 20/1 = 20 [ 1 × 20 (1, 20) 1 and 20 is pair factor of 20]
- 20/2 = 10 [ 2 × 10 (2, 10) 2 and 10 is pair factor of 20]
- 20/4 = 5 [ 4 × 5 (4, 5) 4 and 5 is pair factor of 20]
- 20/5 = 4 [ 5 × 4 (5, 4) 5 and 4 is pair factor of 20]
- 20/10 = 2 [ 10 × 2 (10, 2) 10 and 2 is pair factor of 20]
- 20/20 = 1 [ 20 × 1 (20, 1) 20 and 1 is pair factor of 20]
As we checked numbers between 1 to 20 that are not leaving any remainder, hence we can say factors of 20 is 1, 2, 4, 5, 10, 20.
Also note that, in exponential form prime factorization of 20 is written as 22 × 51 and it is a composite number.
