Lets's calculate LCM of 85,53,539,373
Given numbers has no common factors except 1. So, there LCM is their product i.e 905716735
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/905716735
Therefore, the GCF of Fractions 4/85,17/53,18/539,648/373 is 1/905716735
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 85,53,539,373 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,53,539,373) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(85,53,539,373) x common factors =1 x 1 = 1
LCM(85,53,539,373) = ( 85 × 53 × 539 × 373 ) / 1
LCM(85,53,539,373) = 905716735 / 1
LCM(85,53,539,373) = 905716735
