Least Common Multiple of 40, 80, 744

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

• Least Common Multiple of 40, 80, 744 by common division method
• Least Common Multiple of 40, 80, 744 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 2 x 93 = 7440

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 40,80,744 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,80,744) = 8

common factors(in case of two or more numbers have common factors) = 40

GCF(40,80,744) x common factors =8 x 40 = 320

LCM(40,80,744) = ( 40 × 80 × 744 ) / 320

LCM(40,80,744) = 2380800 / 320

LCM(40,80,744) = 7440

∴ Least Common Multiple of 40,80,744 is 7440

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

• LCM of 49, 42, 686
• LCM of 15, 43, 488
• LCM of 73, 55, 994
• LCM of 60, 48, 481
