Least Common Multiple of 657, 420

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

• Least Common Multiple of 657, 420 by common division method
• Least Common Multiple of 657, 420 with GCF Formula

∴ So the LCM of the given numbers is 3 x 219 x 140 = 91980

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 657,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(657,420) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(657,420) x common factors =3 x 1 = 3

LCM(657,420) = ( 657 × 420 ) / 3

LCM(657,420) = 275940 / 3

LCM(657,420) = 91980

∴ Least Common Multiple of 657,420 is 91980

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

• LCM of 130, 108
• LCM of 401, 825
• LCM of 289, 519
• LCM of 285, 787
• LCM of 110, 223
