Least Common Multiple of 80, 34, 81, 357

Q: How to Find the LCM of 80, 34, 81, 357 ?

Least Common Multiple of 80, 34, 81, 357 = 771120 Step 1: Divide all the numbers with common prime numbers having remainder zero. Step 2: Then multiply all the prime factors with last row quotient of common division that is LCM(80, 34, 81, 357) = 2 x 2 x 2 x 2 x 3 x 3 x 3 x 3 x 5 x 7 x 17 = 771120.

Least Common Multiple of 80, 34, 81, 357 with GCF Formula

Least Common Multiple of 80,34,81,357

Least Common Multiple (LCM) of 80,34,81,357 is 771120

2	80, 34, 81, 357
3	40, 17, 81, 357
17	40, 17, 27, 119
	40, 1, 27, 7

∴ So the LCM of the given numbers is 2 x 3 x 17 x 40 x 1 x 27 x 7 = 771120

Least Common Multiple of 80,34,81,357 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 80,34,81,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,34,81,357) = 1

common factors(in case of two or more numbers have common factors) = 102

GCF(80,34,81,357) x common factors =1 x 102 = 102

LCM(80,34,81,357) = ( 80 × 34 × 81 × 357 ) / 102

LCM(80,34,81,357) = 78654240 / 102

LCM(80,34,81,357) = 771120

∴ Least Common Multiple of 80,34,81,357 is 771120
