Greatest Common Factor
We found the factors 772,245 . The biggest common factor number is the GCF number.
So the greatest common factor 772,245 is 1.
Lets's calculate LCM of 355,879
Given numbers has no common factors except 1. So, there LCM is their product i.e 312045
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/312045
Therefore, the GCF of Fractions 772/355,245/879 is 1/312045
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 355,879 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(355,879) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(355,879) x common factors =1 x 1 = 1
LCM(355,879) = ( 355 × 879 ) / 1
LCM(355,879) = 312045 / 1
LCM(355,879) = 312045
