Least Common Multiple of 18, 45, 70, 819

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

• Least Common Multiple of 18, 45, 70, 819 by common division method
• Least Common Multiple of 18, 45, 70, 819 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 7 x 1 x 1 x 1 x 13 = 8190

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 18,45,70,819 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,45,70,819) = 1

common factors(in case of two or more numbers have common factors) = 5670

GCF(18,45,70,819) x common factors =1 x 5670 = 5670

LCM(18,45,70,819) = ( 18 × 45 × 70 × 819 ) / 5670

LCM(18,45,70,819) = 46437300 / 5670

LCM(18,45,70,819) = 8190

∴ Least Common Multiple of 18,45,70,819 is 8190
