Least Common Multiple of 78, 40, 455

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

• Least Common Multiple of 78, 40, 455 by common division method
• Least Common Multiple of 78, 40, 455 with GCF Formula

∴ So the LCM of the given numbers is 2 x 5 x 13 x 3 x 4 x 7 = 10920

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 78,40,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,40,455) = 1

common factors(in case of two or more numbers have common factors) = 130

GCF(78,40,455) x common factors =1 x 130 = 130

LCM(78,40,455) = ( 78 × 40 × 455 ) / 130

LCM(78,40,455) = 1419600 / 130

LCM(78,40,455) = 10920

∴ Least Common Multiple of 78,40,455 is 10920

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

• LCM of 32, 56, 352
• LCM of 21, 33, 562
• LCM of 79, 44, 475
• LCM of 16, 79, 409
