Greatest Common Factor
We found the factors 80,428,352 . The biggest common factor number is the GCF number.
So the greatest common factor 80,428,352 is 4.
Lets's calculate LCM of 31,89,544
Given numbers has no common factors except 1. So, there LCM is their product i.e 1500896
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1500896
Therefore, the GCF of Fractions 80/31,428/89,352/544 is 4/1500896
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 31,89,544 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,89,544) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,89,544) x common factors =1 x 1 = 1
LCM(31,89,544) = ( 31 × 89 × 544 ) / 1
LCM(31,89,544) = 1500896 / 1
LCM(31,89,544) = 1500896
