What is the LCM of 77, 91 and 143?

What's the Least Common Multiple (LCM) of 77, 91 and 143?

Answer

LCM of 77, 91 and 143 is

1,001

First common multiples: 1,001; 2,002; 3,003; …

1,001 is divisible by all three: 1,001 ÷ 77 = 13; 1,001 ÷ 91 = 11; 1,001 ÷ 143 = 7 — and 13, 11 and 7 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/77 by 13 and of y/91 by 11 and of z/143 by 7.

77 = 7 × 11

91 = 7 × 13

143 = 11 × 13

Prime	77	91	143	Highest power
7	7	7	—	7
11	11	—	11	11
13	—	13	13	13

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 7 × 11 × 13 = 1,001
