:1,2,4,5,8,10,11,16,20,22,32,40,44,55,80,88,110,160,176,220,352,440,880,1760
Greatest Common Factor
We found the factors 3880,1760 . The biggest common factor number is the GCF number.
So the greatest common factor 3880,1760 is 40.
Lets's calculate LCM of 379,398
Given numbers has no common factors except 1. So, there LCM is their product i.e 150842
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/150842
Therefore, the GCF of Fractions 3880/379,1760/398 is 40/150842
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 379,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(379,398) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(379,398) x common factors =1 x 1 = 1
LCM(379,398) = ( 379 × 398 ) / 1
LCM(379,398) = 150842 / 1
LCM(379,398) = 150842
