Least Common Multiple of 90, 42, 305

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

• Least Common Multiple of 90, 42, 305 by common division method
• Least Common Multiple of 90, 42, 305 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 7 x 61 = 38430

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 90,42,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,42,305) = 1

common factors(in case of two or more numbers have common factors) = 30

GCF(90,42,305) x common factors =1 x 30 = 30

LCM(90,42,305) = ( 90 × 42 × 305 ) / 30

LCM(90,42,305) = 1152900 / 30

LCM(90,42,305) = 38430

∴ Least Common Multiple of 90,42,305 is 38430

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

• LCM of 93, 24, 124
• LCM of 86, 64, 191
• LCM of 79, 61, 560
