Least Common Multiple of 40, 7, 66, 56

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

• Least Common Multiple of 40, 7, 66, 56 by common division method
• Least Common Multiple of 40, 7, 66, 56 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 5 x 1 x 33 x 1 = 9240

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 40,7,66,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,7,66,56) = 1

common factors(in case of two or more numbers have common factors) = 112

GCF(40,7,66,56) x common factors =1 x 112 = 112

LCM(40,7,66,56) = ( 40 × 7 × 66 × 56 ) / 112

LCM(40,7,66,56) = 1034880 / 112

LCM(40,7,66,56) = 9240

∴ Least Common Multiple of 40,7,66,56 is 9240

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

• LCM of 24, 9, 35, 78
• LCM of 92, 3, 15, 59
