Greatest Common Factor
We found the factors 2155,6911 . The biggest common factor number is the GCF number.
So the greatest common factor 2155,6911 is 1.
Lets's calculate LCM of 257,764
Given numbers has no common factors except 1. So, there LCM is their product i.e 196348
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/196348
Therefore, the GCF of Fractions 2155/257,6911/764 is 1/196348
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 257,764 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,764) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,764) x common factors =1 x 1 = 1
LCM(257,764) = ( 257 × 764 ) / 1
LCM(257,764) = 196348 / 1
LCM(257,764) = 196348
