So the greatest common factor 492,798 is 6.
Lets's calculate LCM of 391,392
Given numbers has no common factors except 1. So, there LCM is their product i.e 153272
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/153272
Therefore, the GCF of Fractions 492/391,798/392 is 6/153272
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 391,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,392) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,392) x common factors =1 x 1 = 1
LCM(391,392) = ( 391 × 392 ) / 1
LCM(391,392) = 153272 / 1
LCM(391,392) = 153272
