Greatest Common Factor
We found the factors 615,386 . The biggest common factor number is the GCF number.
So the greatest common factor 615,386 is 1.
Lets's calculate LCM of 915,667
Given numbers has no common factors except 1. So, there LCM is their product i.e 610305
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/610305
Therefore, the GCF of Fractions 615/915,386/667 is 1/610305
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 915,667 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(915,667) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(915,667) x common factors =1 x 1 = 1
LCM(915,667) = ( 915 × 667 ) / 1
LCM(915,667) = 610305 / 1
LCM(915,667) = 610305
