Least Common Multiple of 70, 21, 680, 768

Q: How to Find the LCM of 70, 21, 680, 768 ?

Least Common Multiple of 70, 21, 680, 768 = 456960 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(70, 21, 680, 768) = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 7 x 17 = 456960.

Least Common Multiple of 70,21,680,768 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 70,21,680,768 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,21,680,768) = 1

common factors(in case of two or more numbers have common factors) = 1680

GCF(70,21,680,768) x common factors =1 x 1680 = 1680

LCM(70,21,680,768) = ( 70 × 21 × 680 × 768 ) / 1680

LCM(70,21,680,768) = 767692800 / 1680

LCM(70,21,680,768) = 456960

∴ Least Common Multiple of 70,21,680,768 is 456960
