Greatest Common Factor
We found the factors 75,55,745 . The biggest common factor number is the GCF number.
So the greatest common factor 75,55,745 is 5.
Lets's calculate LCM of 908,511,905
Given numbers has no common factors except 1. So, there LCM is their product i.e 419909140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/419909140
Therefore, the GCF of Fractions 75/908,55/511,745/905 is 5/419909140
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 908,511,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(908,511,905) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(908,511,905) x common factors =1 x 1 = 1
LCM(908,511,905) = ( 908 × 511 × 905 ) / 1
LCM(908,511,905) = 419909140 / 1
LCM(908,511,905) = 419909140
