Least Common Multiple of 345, 615, 69

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

• Least Common Multiple of 345, 615, 69 by common division method
• Least Common Multiple of 345, 615, 69 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 23 x 1 x 41 x 1 = 14145

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 345,615,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(345,615,69) = 3

common factors(in case of two or more numbers have common factors) = 345

GCF(345,615,69) x common factors =3 x 345 = 1035

LCM(345,615,69) = ( 345 × 615 × 69 ) / 1035

LCM(345,615,69) = 14640075 / 1035

LCM(345,615,69) = 14145

∴ Least Common Multiple of 345,615,69 is 14145

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

• LCM of 456, 111, 15
• LCM of 991, 542, 78
