100

${\huge{\pink{\underline{\underline{Explanation:}}}}}$

You have to do prime factorisation for each number...

Alternatively, the lcm of 20 and 25 can be found using the prime factorization of 20 and 25...

• The prime factorization of 20 is: 2 x 2 x 5.

• The prime factorization of 25 is: 5 x 5.

• Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get LCM (20,20) = 100.
