    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!

    26=2*13

    65=5*13

    10=2*5

    Therefore LCM=2*5*13=130

    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.

    26 = 2x13

    65 = 5x13

    10 = 2x 5

    2x5x13 = 130
