Least Common Multiple of 42, 18, 21, 16, 99

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

• Least Common Multiple of 42, 18, 21, 16, 99 by common division method
• Least Common Multiple of 42, 18, 21, 16, 99 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 1 x 1 x 1 x 8 x 11 = 11088

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 42,18,21,16,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,18,21,16,99) = 1

common factors(in case of two or more numbers have common factors) = 2268

GCF(42,18,21,16,99) x common factors =1 x 2268 = 2268

LCM(42,18,21,16,99) = ( 42 × 18 × 21 × 16 × 99 ) / 2268

LCM(42,18,21,16,99) = 25147584 / 2268

LCM(42,18,21,16,99) = 11088

∴ Least Common Multiple of 42,18,21,16,99 is 11088
