1,2,359,718
Greatest Common Factor
We found the factors 84,90,89,718 . The biggest common factor number is the GCF number.
So the greatest common factor 84,90,89,718 is 1.
Lets's calculate LCM of 32,19,47,93
Given numbers has no common factors except 1. So, there LCM is their product i.e 2657568
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2657568
Therefore, the GCF of Fractions 84/32,90/19,89/47,718/93 is 1/2657568
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 32,19,47,93 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,19,47,93) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(32,19,47,93) x common factors =1 x 1 = 1
LCM(32,19,47,93) = ( 32 × 19 × 47 × 93 ) / 1
LCM(32,19,47,93) = 2657568 / 1
LCM(32,19,47,93) = 2657568
