Least Common Multiple of 21, 67, 103

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

• Least Common Multiple of 21, 67, 103 by common division method
• Least Common Multiple of 21, 67, 103 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 144921

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 21,67,103 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,67,103) = 1

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

GCF(21,67,103) x common factors =1 x 1 = 1

LCM(21,67,103) = ( 21 × 67 × 103 ) / 1

LCM(21,67,103) = 144921 / 1

LCM(21,67,103) = 144921

∴ Least Common Multiple of 21,67,103 is 144921

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

• LCM of 55, 68, 927
• LCM of 51, 27, 813
• LCM of 17, 60, 804
• LCM of 68, 10, 348
