Least Common Multiple of 63, 70, 140

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

• Least Common Multiple of 63, 70, 140 by common division method
• Least Common Multiple of 63, 70, 140 with GCF Formula

∴ So the LCM of the given numbers is 2 x 5 x 7 x 9 x 1 x 2 = 1260

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 63,70,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,70,140) = 7

common factors(in case of two or more numbers have common factors) = 70

GCF(63,70,140) x common factors =7 x 70 = 490

LCM(63,70,140) = ( 63 × 70 × 140 ) / 490

LCM(63,70,140) = 617400 / 490

LCM(63,70,140) = 1260

∴ Least Common Multiple of 63,70,140 is 1260

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

• LCM of 33, 45, 486
• LCM of 71, 45, 966
