LCM-least common multiple help?

Favorite Answer

First, find the prime factorization of each number:

.....26.........65.........10
... /...\......../...\......../....\.............................................................
..13..2.....5....13...2......5

Second, look at all the different prime numbers that you've got:
2, 5, 13

Last, multiply these together:
2x5x13=130

So your answer is 130!...Show more

26=2*13
65=5*13
10=2*5
Therefore LCM=2*5*13=130...Show more

The LCM for 36 and 42 would be 252...Show more

LCM(26, 65 and 10) = 2*5*13 = 130
26, 65, 10| 2
13, 65, 05| 5
13, 13, 01| 13
01, 01, 01

26 = 2(13)

65 = 5(13)

10 = 5(2)

LCM = 2(13)(5)

..........= 130

You need one of each different number....Show more
