Least Common Multiple of 75, 42, 670

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

• Least Common Multiple of 75, 42, 670 by common division method
• Least Common Multiple of 75, 42, 670 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 5 x 7 x 67 = 70350

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 75,42,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,42,670) = 1

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

GCF(75,42,670) x common factors =1 x 30 = 30

LCM(75,42,670) = ( 75 × 42 × 670 ) / 30

LCM(75,42,670) = 2110500 / 30

LCM(75,42,670) = 70350

∴ Least Common Multiple of 75,42,670 is 70350

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

• LCM of 80, 40, 349
• LCM of 23, 16, 643
• LCM of 84, 51, 863
• LCM of 91, 94, 310
