Least Common Multiple of 35, 42, 90

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

• Least Common Multiple of 35, 42, 90 by common division method
• Least Common Multiple of 35, 42, 90 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 1 x 3 = 630

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 35,42,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(35,42,90) = 1

common factors(in case of two or more numbers have common factors) = 210

GCF(35,42,90) x common factors =1 x 210 = 210

LCM(35,42,90) = ( 35 × 42 × 90 ) / 210

LCM(35,42,90) = 132300 / 210

LCM(35,42,90) = 630

∴ Least Common Multiple of 35,42,90 is 630

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

• LCM of 27, 17, 55
• LCM of 71, 83, 14
• LCM of 65, 63, 34
• LCM of 77, 13, 92
