#ProblemCorrect AnswerYour Answer
112, 15
Solution
The GCF is 3.
LCM(12,15) = product / gcf = (12 * 15) / 3.
= (12/3) * 15
= 4 * 15.
= 60.
#ProblemCorrect AnswerYour Answer
29, 15
Solution
The GCF is 3.
LCM(9,15) = product / gcf = (9 * 15) / 3.
= (9/3) * 15
= 3 * 15.
= 45.

#ProblemCorrect AnswerYour Answer
120, 12
Solution
The GCF is 4.
LCM(20,12) = product / gcf = (20 * 12) / 4.
= (20/4) * 12
= 5 * 12.
= 60.
#ProblemCorrect AnswerYour Answer
212, 20
Solution
The GCF is 4.
LCM(12,20) = product / gcf = (12 * 20) / 4.
= (12/4) * 20
= 3 * 20.
= 60.
