LCM of 21, 57, 47, 19, 237

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

Least Common Multiple of 21, 57, 47, 19, 237 by common division method
Least Common Multiple of 21, 57, 47, 19, 237 with GCF Formula

Least Common Multiple of 21,57,47,19,237

Least Common Multiple (LCM) of 21,57,47,19,237 is 1481487

3	21, 57, 47, 19, 237
19	7, 19, 47, 19, 79
	7, 1, 47, 1, 79

∴ So the LCM of the given numbers is 3 x 19 x 7 x 1 x 47 x 1 x 79 = 1481487

Least Common Multiple of 21,57,47,19,237 with GCF Formula

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

We need to calculate greatest common factor of 21,57,47,19,237 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,57,47,19,237) = 1

common factors(in case of two or more numbers have common factors) = 171

GCF(21,57,47,19,237) x common factors =1 x 171 = 171

LCM(21,57,47,19,237) = ( 21 × 57 × 47 × 19 × 237 ) / 171

LCM(21,57,47,19,237) = 253334277 / 171

LCM(21,57,47,19,237) = 1481487

∴ Least Common Multiple of 21,57,47,19,237 is 1481487
