Least Common Multiple of 28, 28, 42, 98

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

• Least Common Multiple of 28, 28, 42, 98 by common division method
• Least Common Multiple of 28, 28, 42, 98 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 1 x 3 x 7 = 588

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 28,28,42,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,28,42,98) = 14

common factors(in case of two or more numbers have common factors) = 392

GCF(28,28,42,98) x common factors =14 x 392 = 5488

LCM(28,28,42,98) = ( 28 × 28 × 42 × 98 ) / 5488

LCM(28,28,42,98) = 3226944 / 5488

LCM(28,28,42,98) = 588

∴ Least Common Multiple of 28,28,42,98 is 588

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