Answer

200

Work Step by Step

First, we express each number as a product of prime factors: $40=2\times2\times2\times5$ $100=2\times2\times5\times5$ The least common multiple includes each different prime factor as many times as the most times it appears in one of the factorizations. The most times 2 appears is three times The most times 5 appears is twice. LCM$=2\times2\times2\times5\times5=200$
