The factors of 20 are:
20, because 20 ∙ 1 = 20
40, because 20 ∙ 2 = 40
60, because 20 ∙ 3 = 60
80, because 20 ∙ 4 = 80
100, because 20 ∙ 5 = 100
120, because 20 ∙ 6 = 120
etc.
The factors of 25 are:
25, because 25 ∙ 1 = 25
50, because 25 ∙ 2 = 50
75, because 25 ∙ 3 = 75
100, because 25 ∙ 4 = 100
125, because 25 ∙ 5 = 125
etc.

LCM of 25and 20
2 answers
20 = 2^2 * 5
25 = 5^2
the LCM has the highest powers of all the primes involved
2^2 * 5^2 = 100
25 = 5^2
the LCM has the highest powers of all the primes involved
2^2 * 5^2 = 100
