Least Common Multiple of 85, 21, 90, 34

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

• Least Common Multiple of 85, 21, 90, 34 by common division method
• Least Common Multiple of 85, 21, 90, 34 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 17 x 1 x 7 x 3 x 1 = 10710

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 85,21,90,34 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(85,21,90,34) = 1

common factors(in case of two or more numbers have common factors) = 510

GCF(85,21,90,34) x common factors =1 x 510 = 510

LCM(85,21,90,34) = ( 85 × 21 × 90 × 34 ) / 510

LCM(85,21,90,34) = 5462100 / 510

LCM(85,21,90,34) = 10710

∴ Least Common Multiple of 85,21,90,34 is 10710

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