Least Common Multiple of 35, 56, 420

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

• Least Common Multiple of 35, 56, 420 by common division method
• Least Common Multiple of 35, 56, 420 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 2 x 3 = 840

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 35,56,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(35,56,420) = 7

common factors(in case of two or more numbers have common factors) = 140

GCF(35,56,420) x common factors =7 x 140 = 980

LCM(35,56,420) = ( 35 × 56 × 420 ) / 980

LCM(35,56,420) = 823200 / 980

LCM(35,56,420) = 840

∴ Least Common Multiple of 35,56,420 is 840

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

• LCM of 36, 17, 941
• LCM of 62, 43, 495
• LCM of 47, 61, 263
