Least Common Multiple of 1185, 1720

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

• Least Common Multiple of 1185, 1720 by common division method
• Least Common Multiple of 1185, 1720 with GCF Formula

∴ So the LCM of the given numbers is 5 x 237 x 344 = 407640

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 1185,1720 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1185,1720) = 5

common factors(in case of two or more numbers have common factors) = 1

GCF(1185,1720) x common factors =5 x 1 = 5

LCM(1185,1720) = ( 1185 × 1720 ) / 5

LCM(1185,1720) = 2038200 / 5

LCM(1185,1720) = 407640

∴ Least Common Multiple of 1185,1720 is 407640

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

• LCM of 5577, 2450
• LCM of 8664, 7695
• LCM of 8602, 1999
• LCM of 2349, 6985
