Least Common Multiple of 20, 28, 109

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

• Least Common Multiple of 20, 28, 109 by common division method
• Least Common Multiple of 20, 28, 109 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 109 = 15260

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 20,28,109 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,28,109) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(20,28,109) x common factors =1 x 4 = 4

LCM(20,28,109) = ( 20 × 28 × 109 ) / 4

LCM(20,28,109) = 61040 / 4

LCM(20,28,109) = 15260

∴ Least Common Multiple of 20,28,109 is 15260

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

• LCM of 75, 40, 659
• LCM of 95, 80, 898
• LCM of 49, 60, 687
