Greatest Common Factor
We found the factors 165,440 . The biggest common factor number is the GCF number.
So the greatest common factor 165,440 is 55.
Lets's calculate LCM of 298,757
Given numbers has no common factors except 1. So, there LCM is their product i.e 225586
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 55/225586
Therefore, the GCF of Fractions 165/298,440/757 is 55/225586
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 298,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(298,757) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(298,757) x common factors =1 x 1 = 1
LCM(298,757) = ( 298 × 757 ) / 1
LCM(298,757) = 225586 / 1
LCM(298,757) = 225586
