Least Common Multiple of 21, 85, 135

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

• Least Common Multiple of 21, 85, 135 by common division method
• Least Common Multiple of 21, 85, 135 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 7 x 17 x 9 = 16065

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 21,85,135 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,85,135) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(21,85,135) x common factors =1 x 15 = 15

LCM(21,85,135) = ( 21 × 85 × 135 ) / 15

LCM(21,85,135) = 240975 / 15

LCM(21,85,135) = 16065

∴ Least Common Multiple of 21,85,135 is 16065

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

• LCM of 83, 25, 619
• LCM of 92, 19, 635
