Least Common Multiple of 17, 21, 643

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

• Least Common Multiple of 17, 21, 643 by common division method
• Least Common Multiple of 17, 21, 643 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 229551

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 17,21,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,21,643) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(17,21,643) x common factors =1 x 1 = 1

LCM(17,21,643) = ( 17 × 21 × 643 ) / 1

LCM(17,21,643) = 229551 / 1

LCM(17,21,643) = 229551

∴ Least Common Multiple of 17,21,643 is 229551

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

• LCM of 69, 42, 402
• LCM of 66, 18, 506
• LCM of 23, 31, 900
• LCM of 44, 12, 204
