Least Common Multiple of 28, 55, 781

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

• Least Common Multiple of 28, 55, 781 by common division method
• Least Common Multiple of 28, 55, 781 with GCF Formula

∴ So the LCM of the given numbers is 11 x 28 x 5 x 71 = 109340

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 28,55,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,55,781) = 1

common factors(in case of two or more numbers have common factors) = 11

GCF(28,55,781) x common factors =1 x 11 = 11

LCM(28,55,781) = ( 28 × 55 × 781 ) / 11

LCM(28,55,781) = 1202740 / 11

LCM(28,55,781) = 109340

∴ Least Common Multiple of 28,55,781 is 109340

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

• LCM of 23, 16, 643
• LCM of 63, 99, 191
• LCM of 89, 97, 993
