Least Common Multiple of 21, 38, 869

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

• Least Common Multiple of 21, 38, 869 by common division method
• Least Common Multiple of 21, 38, 869 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 693462

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 21,38,869 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,38,869) = 1

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

GCF(21,38,869) x common factors =1 x 1 = 1

LCM(21,38,869) = ( 21 × 38 × 869 ) / 1

LCM(21,38,869) = 693462 / 1

LCM(21,38,869) = 693462

∴ Least Common Multiple of 21,38,869 is 693462

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

• LCM of 70, 83, 753
• LCM of 96, 14, 677
• LCM of 31, 12, 273
• LCM of 52, 71, 178
