Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 7, 31, 68, 42, 16 i.e. 177072 smallest integer divisible by all numbers.

Least common multiple (LCM) of 7, 31, 68, 42, 16 is 177072.

LCM(7, 31, 68, 42, 16) = 177072

LCM of 7, 31, 68, 42, 16

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 7,31,68,42,16

Least Common Multiple (LCM) of 7,31,68,42,16 is 177072

2 7, 31, 68, 42, 16
2 7, 31, 34, 21, 8
7 7, 31, 17, 21, 4
1, 31, 17, 3, 4

∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 31 x 17 x 3 x 4 = 177072

Least Common Multiple of 7,31,68,42,16 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 7,31,68,42,16 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7,31,68,42,16) = 1

common factors(in case of two or more numbers have common factors) = 56

GCF(7,31,68,42,16) x common factors =1 x 56 = 56

LCM(7,31,68,42,16) = ( 7 × 31 × 68 × 42 × 16 ) / 56

LCM(7,31,68,42,16) = 9916032 / 56

LCM(7,31,68,42,16) = 177072

∴ Least Common Multiple of 7,31,68,42,16 is 177072
