Least Common Multiple of 135, 42

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

• Least Common Multiple of 135, 42 by common division method
• Least Common Multiple of 135, 42 with GCF Formula

∴ So the LCM of the given numbers is 3 x 45 x 14 = 1890

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 135,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(135,42) = 3

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

GCF(135,42) x common factors =3 x 1 = 3

LCM(135,42) = ( 135 × 42 ) / 3

LCM(135,42) = 5670 / 3

LCM(135,42) = 1890

∴ Least Common Multiple of 135,42 is 1890

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

• LCM of 971, 71
• LCM of 839, 20
• LCM of 571, 67
• LCM of 548, 24
• LCM of 372, 85
