Answer:
100
Step-by-step explanation:
In order to find the least common multiple of 20 and 25, first find the prime factors of 20 and 25.
20 = 2*2*5
25 = 5*5
Here,
Common factor = 5
Uncommon factors = 2, 2, 5
Least common multiple of 20 and 25 = Common factors* Uncommon factors
= 5*(2*2*5)
= 5*20
= 100
