Least Common Multiple of 45, 57, 405

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

• Least Common Multiple of 45, 57, 405 by common division method
• Least Common Multiple of 45, 57, 405 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 5 x 1 x 19 x 9 = 7695

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 45,57,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,57,405) = 3

common factors(in case of two or more numbers have common factors) = 45

GCF(45,57,405) x common factors =3 x 45 = 135

LCM(45,57,405) = ( 45 × 57 × 405 ) / 135

LCM(45,57,405) = 1038825 / 135

LCM(45,57,405) = 7695

∴ Least Common Multiple of 45,57,405 is 7695

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

• LCM of 87, 37, 936
• LCM of 25, 97, 260
