Greatest Common Factor
We found the factors 248,253 . The biggest common factor number is the GCF number.
So the greatest common factor 248,253 is 1.
Lets's calculate LCM of 388,717
Given numbers has no common factors except 1. So, there LCM is their product i.e 278196
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/278196
Therefore, the GCF of Fractions 248/388,253/717 is 1/278196
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 388,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(388,717) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(388,717) x common factors =1 x 1 = 1
LCM(388,717) = ( 388 × 717 ) / 1
LCM(388,717) = 278196 / 1
LCM(388,717) = 278196
