Least Common Multiple of 75, 100, 780

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

• Least Common Multiple of 75, 100, 780 by common division method
• Least Common Multiple of 75, 100, 780 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 5 x 1 x 1 x 13 = 3900

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 75,100,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,100,780) = 5

common factors(in case of two or more numbers have common factors) = 300

GCF(75,100,780) x common factors =5 x 300 = 1500

LCM(75,100,780) = ( 75 × 100 × 780 ) / 1500

LCM(75,100,780) = 5850000 / 1500

LCM(75,100,780) = 3900

∴ Least Common Multiple of 75,100,780 is 3900

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

• LCM of 76, 910, 394
• LCM of 48, 216, 351
• LCM of 96, 463, 235
• LCM of 43, 292, 120
• LCM of 39, 746, 737
