Least Common Multiple of 28, 30, 14, 220

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

• Least Common Multiple of 28, 30, 14, 220 by common division method
• Least Common Multiple of 28, 30, 14, 220 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 3 x 1 x 11 = 4620

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 28,30,14,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,30,14,220) = 2

common factors(in case of two or more numbers have common factors) = 280

GCF(28,30,14,220) x common factors =2 x 280 = 560

LCM(28,30,14,220) = ( 28 × 30 × 14 × 220 ) / 560

LCM(28,30,14,220) = 2587200 / 560

LCM(28,30,14,220) = 4620

∴ Least Common Multiple of 28,30,14,220 is 4620
