Greatest Common Factor
We found the factors 687,534,390 . The biggest common factor number is the GCF number.
So the greatest common factor 687,534,390 is 3.
Lets's calculate LCM of 28,97,939
Given numbers has no common factors except 1. So, there LCM is their product i.e 2550324
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2550324
Therefore, the GCF of Fractions 687/28,534/97,390/939 is 3/2550324
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 28,97,939 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,97,939) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(28,97,939) x common factors =1 x 1 = 1
LCM(28,97,939) = ( 28 × 97 × 939 ) / 1
LCM(28,97,939) = 2550324 / 1
LCM(28,97,939) = 2550324
