Least Common Multiple of 84, 20, 28, 430

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

• Least Common Multiple of 84, 20, 28, 430 by common division method
• Least Common Multiple of 84, 20, 28, 430 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 3 x 1 x 1 x 43 = 18060

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 84,20,28,430 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,20,28,430) = 2

common factors(in case of two or more numbers have common factors) = 560

GCF(84,20,28,430) x common factors =2 x 560 = 1120

LCM(84,20,28,430) = ( 84 × 20 × 28 × 430 ) / 1120

LCM(84,20,28,430) = 20227200 / 1120

LCM(84,20,28,430) = 18060

∴ Least Common Multiple of 84,20,28,430 is 18060
