Least Common Multiple of 19, 64, 87, 689

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

• Least Common Multiple of 19, 64, 87, 689 by common division method
• Least Common Multiple of 19, 64, 87, 689 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 72890688

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 19,64,87,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(19,64,87,689) = 1

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

GCF(19,64,87,689) x common factors =1 x 1 = 1

LCM(19,64,87,689) = ( 19 × 64 × 87 × 689 ) / 1

LCM(19,64,87,689) = 72890688 / 1

LCM(19,64,87,689) = 72890688

∴ Least Common Multiple of 19,64,87,689 is 72890688
