Least Common Multiple of 638, 2420

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

• Least Common Multiple of 638, 2420 by common division method
• Least Common Multiple of 638, 2420 with GCF Formula

∴ So the LCM of the given numbers is 2 x 11 x 29 x 110 = 70180

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 638,2420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(638,2420) = 22

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

GCF(638,2420) x common factors =22 x 1 = 22

LCM(638,2420) = ( 638 × 2420 ) / 22

LCM(638,2420) = 1543960 / 22

LCM(638,2420) = 70180

∴ Least Common Multiple of 638,2420 is 70180

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

• LCM of 298, 1550
• LCM of 297, 4708
• LCM of 522, 9575
• LCM of 585, 7066
• LCM of 702, 3899
