Least Common Multiple of 33, 21, 247

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

• Least Common Multiple of 33, 21, 247 by common division method
• Least Common Multiple of 33, 21, 247 with GCF Formula

∴ So the LCM of the given numbers is 3 x 11 x 7 x 247 = 57057

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 33,21,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(33,21,247) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(33,21,247) x common factors =1 x 3 = 3

LCM(33,21,247) = ( 33 × 21 × 247 ) / 3

LCM(33,21,247) = 171171 / 3

LCM(33,21,247) = 57057

∴ Least Common Multiple of 33,21,247 is 57057

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

• LCM of 22, 25, 140
• LCM of 79, 22, 324
• LCM of 28, 21, 302
