Least Common Multiple of 42, 84, 153

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

• Least Common Multiple of 42, 84, 153 by common division method
• Least Common Multiple of 42, 84, 153 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 2 x 51 = 4284

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 42,84,153 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,84,153) = 3

common factors(in case of two or more numbers have common factors) = 42

GCF(42,84,153) x common factors =3 x 42 = 126

LCM(42,84,153) = ( 42 × 84 × 153 ) / 126

LCM(42,84,153) = 539784 / 126

LCM(42,84,153) = 4284

∴ Least Common Multiple of 42,84,153 is 4284

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

• LCM of 76, 18, 701
• LCM of 31, 39, 515
