Least Common Multiple of 645, 178, 621, 221, 129

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

• Least Common Multiple of 645, 178, 621, 221, 129 by common division method
• Least Common Multiple of 645, 178, 621, 221, 129 with GCF Formula

∴ So the LCM of the given numbers is 3 x 43 x 5 x 178 x 207 x 221 x 1 = 5252213070

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 645,178,621,221,129 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,178,621,221,129) = 1

common factors(in case of two or more numbers have common factors) = 387

GCF(645,178,621,221,129) x common factors =1 x 387 = 387

LCM(645,178,621,221,129) = ( 645 × 178 × 621 × 221 × 129 ) / 387

LCM(645,178,621,221,129) = 2032606458090 / 387

LCM(645,178,621,221,129) = 5252213070

∴ Least Common Multiple of 645,178,621,221,129 is 5252213070
