Least Common Multiple of 21, 67, 283

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

• Least Common Multiple of 21, 67, 283 by common division method
• Least Common Multiple of 21, 67, 283 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 398181

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 21,67,283 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,67,283) = 1

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

GCF(21,67,283) x common factors =1 x 1 = 1

LCM(21,67,283) = ( 21 × 67 × 283 ) / 1

LCM(21,67,283) = 398181 / 1

LCM(21,67,283) = 398181

∴ Least Common Multiple of 21,67,283 is 398181

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

• LCM of 12, 80, 202
• LCM of 45, 96, 444
• LCM of 41, 40, 426
• LCM of 28, 86, 703
• LCM of 57, 33, 735
