Greatest Common Factor
We found the factors 61,85,697 . The biggest common factor number is the GCF number.
So the greatest common factor 61,85,697 is 1.
Lets's calculate LCM of 677,371,229
Given numbers has no common factors except 1. So, there LCM is their product i.e 57517243
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57517243
Therefore, the GCF of Fractions 61/677,85/371,697/229 is 1/57517243
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 677,371,229 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(677,371,229) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(677,371,229) x common factors =1 x 1 = 1
LCM(677,371,229) = ( 677 × 371 × 229 ) / 1
LCM(677,371,229) = 57517243 / 1
LCM(677,371,229) = 57517243
