Greatest Common Factor
We found the factors 7,208,665 . The biggest common factor number is the GCF number.
So the greatest common factor 7,208,665 is 1.
Lets's calculate LCM of 39,71,98
Given numbers has no common factors except 1. So, there LCM is their product i.e 271362
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/271362
Therefore, the GCF of Fractions 7/39,208/71,665/98 is 1/271362
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 39,71,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,71,98) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,71,98) x common factors =1 x 1 = 1
LCM(39,71,98) = ( 39 × 71 × 98 ) / 1
LCM(39,71,98) = 271362 / 1
LCM(39,71,98) = 271362
