Least Common Multiple of 30, 84, 21, 93

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

• Least Common Multiple of 30, 84, 21, 93 by common division method
• Least Common Multiple of 30, 84, 21, 93 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 7 x 5 x 2 x 1 x 31 = 13020

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 30,84,21,93 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,84,21,93) = 3

common factors(in case of two or more numbers have common factors) = 126

GCF(30,84,21,93) x common factors =3 x 126 = 378

LCM(30,84,21,93) = ( 30 × 84 × 21 × 93 ) / 378

LCM(30,84,21,93) = 4921560 / 378

LCM(30,84,21,93) = 13020

∴ Least Common Multiple of 30,84,21,93 is 13020

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