:1,2,3,4,6,8,12,16,19,24,38,48,57,76,114,152,228,304,456,912
Greatest Common Factor
We found the factors 128,912 . The biggest common factor number is the GCF number.
So the greatest common factor 128,912 is 16.
Lets's calculate LCM of 377,148
Given numbers has no common factors except 1. So, there LCM is their product i.e 55796
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/55796
Therefore, the GCF of Fractions 128/377,912/148 is 16/55796
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 377,148 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(377,148) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(377,148) x common factors =1 x 1 = 1
LCM(377,148) = ( 377 × 148 ) / 1
LCM(377,148) = 55796 / 1
LCM(377,148) = 55796
