Least Common Multiple of 28, 20, 845

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

• Least Common Multiple of 28, 20, 845 by common division method
• Least Common Multiple of 28, 20, 845 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 169 = 23660

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 28,20,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,20,845) = 1

common factors(in case of two or more numbers have common factors) = 20

GCF(28,20,845) x common factors =1 x 20 = 20

LCM(28,20,845) = ( 28 × 20 × 845 ) / 20

LCM(28,20,845) = 473200 / 20

LCM(28,20,845) = 23660

∴ Least Common Multiple of 28,20,845 is 23660

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

• LCM of 85, 35, 132
• LCM of 10, 11, 377
• LCM of 35, 24, 789
