Least Common Multiple of 21, 47, 47, 847

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

• Least Common Multiple of 21, 47, 47, 847 by common division method
• Least Common Multiple of 21, 47, 47, 847 with GCF Formula

∴ So the LCM of the given numbers is 7 x 47 x 3 x 1 x 1 x 121 = 119427

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 21,47,47,847 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,47,47,847) = 1

common factors(in case of two or more numbers have common factors) = 329

GCF(21,47,47,847) x common factors =1 x 329 = 329

LCM(21,47,47,847) = ( 21 × 47 × 47 × 847 ) / 329

LCM(21,47,47,847) = 39291483 / 329

LCM(21,47,47,847) = 119427

∴ Least Common Multiple of 21,47,47,847 is 119427
