Greatest Common Factor
We found the factors 470,390 . The biggest common factor number is the GCF number.
So the greatest common factor 470,390 is 10.
Lets's calculate LCM of 353,488
Given numbers has no common factors except 1. So, there LCM is their product i.e 172264
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/172264
Therefore, the GCF of Fractions 470/353,390/488 is 10/172264
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 353,488 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(353,488) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(353,488) x common factors =1 x 1 = 1
LCM(353,488) = ( 353 × 488 ) / 1
LCM(353,488) = 172264 / 1
LCM(353,488) = 172264
