Below are sample questions representative of the exercises included on this worksheet and related 5.30 Least Common Multiple skill assessments:

Problem 1Difficulty: Mastery

One exercise repeats every 72 counts and another repeats every 96 counts. What is the smallest number of counts where both patterns line up?

A24 counts

B288 counts

C96 counts

D168 counts

Solution & Explanation:Find the least common multiple of 72 and 96. The first common multiple is 288, so both events happen together again after 288 counts.

Problem 2Difficulty: Mastery

What is the least common multiple (LCM) of 126 and 140?

Solution & Explanation:Find the LCM of 126 and 140. One way: LCM = (126×140) ÷ GCF. The GCF is 14, so LCM = (126×140) ÷ 14 = 1260. That’s the smallest time/size where both patterns match.

Problem 3Difficulty: Mastery

Two machines complete cycles every 70 seconds and 84 seconds. What is the least number of seconds until both cycles finish at the same time?

A420 seconds

B84 seconds

C154 seconds

D14 seconds

Solution & Explanation:Find the least common multiple of 70 and 84. The first common multiple is 420, so both events happen together again after 420 seconds.
