Least Common Multiple of 154, 638, 42

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

• Least Common Multiple of 154, 638, 42 by common division method
• Least Common Multiple of 154, 638, 42 with GCF Formula

∴ So the LCM of the given numbers is 2 x 7 x 11 x 1 x 29 x 3 = 13398

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 154,638,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(154,638,42) = 2

common factors(in case of two or more numbers have common factors) = 154

GCF(154,638,42) x common factors =2 x 154 = 308

LCM(154,638,42) = ( 154 × 638 × 42 ) / 308

LCM(154,638,42) = 4126584 / 308

LCM(154,638,42) = 13398

∴ Least Common Multiple of 154,638,42 is 13398

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

• LCM of 220, 236, 80
• LCM of 307, 466, 14
• LCM of 300, 587, 19
