Least Common Multiple of 40, 20, 386

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

• Least Common Multiple of 40, 20, 386 by common division method
• Least Common Multiple of 40, 20, 386 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 2 x 193 = 7720

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 40,20,386 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,20,386) = 2

common factors(in case of two or more numbers have common factors) = 20

GCF(40,20,386) x common factors =2 x 20 = 40

LCM(40,20,386) = ( 40 × 20 × 386 ) / 40

LCM(40,20,386) = 308800 / 40

LCM(40,20,386) = 7720

∴ Least Common Multiple of 40,20,386 is 7720

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 42, 94, 950
• LCM of 49, 61, 214
• LCM of 57, 37, 696
