So the greatest common factor 405,845 is 5.
Lets's calculate LCM of 118,273
Given numbers has no common factors except 1. So, there LCM is their product i.e 32214
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/32214
Therefore, the GCF of Fractions 405/118,845/273 is 5/32214
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 118,273 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(118,273) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(118,273) x common factors =1 x 1 = 1
LCM(118,273) = ( 118 × 273 ) / 1
LCM(118,273) = 32214 / 1
LCM(118,273) = 32214
