Least Common Multiple of 678, 721

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

• Least Common Multiple of 678, 721 by common division method
• Least Common Multiple of 678, 721 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 488838

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 678,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(678,721) = 1

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

GCF(678,721) x common factors =1 x 1 = 1

LCM(678,721) = ( 678 × 721 ) / 1

LCM(678,721) = 488838 / 1

LCM(678,721) = 488838

∴ Least Common Multiple of 678,721 is 488838

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

• LCM of 164, 181
• LCM of 917, 289
• LCM of 252, 862
• LCM of 583, 372
• LCM of 130, 211
