Least Common Multiple of 780, 750, 30

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

• Least Common Multiple of 780, 750, 30 by common division method
• Least Common Multiple of 780, 750, 30 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 26 x 25 x 1 = 19500

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 780,750,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(780,750,30) = 30

common factors(in case of two or more numbers have common factors) = 30

GCF(780,750,30) x common factors =30 x 30 = 900

LCM(780,750,30) = ( 780 × 750 × 30 ) / 900

LCM(780,750,30) = 17550000 / 900

LCM(780,750,30) = 19500

∴ Least Common Multiple of 780,750,30 is 19500

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

• LCM of 775, 697, 51
• LCM of 410, 986, 76
• LCM of 633, 954, 56
• LCM of 342, 994, 60
• LCM of 108, 163, 63
