Least Common Multiple of 30, 23, 915

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

• Least Common Multiple of 30, 23, 915 by common division method
• Least Common Multiple of 30, 23, 915 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 2 x 23 x 61 = 42090

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 30,23,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,23,915) = 1

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

GCF(30,23,915) x common factors =1 x 15 = 15

LCM(30,23,915) = ( 30 × 23 × 915 ) / 15

LCM(30,23,915) = 631350 / 15

LCM(30,23,915) = 42090

∴ Least Common Multiple of 30,23,915 is 42090

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