Least Common Multiple of 21, 61, 434, 451

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

• Least Common Multiple of 21, 61, 434, 451 by common division method
• Least Common Multiple of 21, 61, 434, 451 with GCF Formula

∴ So the LCM of the given numbers is 7 x 3 x 61 x 62 x 451 = 35819322

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 21,61,434,451 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,61,434,451) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(21,61,434,451) x common factors =1 x 7 = 7

LCM(21,61,434,451) = ( 21 × 61 × 434 × 451 ) / 7

LCM(21,61,434,451) = 250735254 / 7

LCM(21,61,434,451) = 35819322

∴ Least Common Multiple of 21,61,434,451 is 35819322
