Greatest Common Factor
We found the factors 638,696,222 . The biggest common factor number is the GCF number.
So the greatest common factor 638,696,222 is 2.
Lets's calculate LCM of 49,79,701
Given numbers has no common factors except 1. So, there LCM is their product i.e 2713571
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2713571
Therefore, the GCF of Fractions 638/49,696/79,222/701 is 2/2713571
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 49,79,701 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,79,701) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,79,701) x common factors =1 x 1 = 1
LCM(49,79,701) = ( 49 × 79 × 701 ) / 1
LCM(49,79,701) = 2713571 / 1
LCM(49,79,701) = 2713571
