Least Common Multiple of 16, 19, 21

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

• Least Common Multiple of 16, 19, 21 by common division method
• Least Common Multiple of 16, 19, 21 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 6384

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 16,19,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(16,19,21) = 1

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

GCF(16,19,21) x common factors =1 x 1 = 1

LCM(16,19,21) = ( 16 × 19 × 21 ) / 1

LCM(16,19,21) = 6384 / 1

LCM(16,19,21) = 6384

∴ Least Common Multiple of 16,19,21 is 6384

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

• LCM of 45, 92, 45
• LCM of 66, 16, 26
• LCM of 35, 33, 73
• LCM of 44, 54, 16
• LCM of 41, 30, 38
