Greatest Common Factor
We found the factors 457,107 . The biggest common factor number is the GCF number.
So the greatest common factor 457,107 is 1.
Lets's calculate LCM of 616,903
7 | 616, 903 |
88, 129 |
∴ So the LCM of the given numbers is 7 x 88 x 129 = 79464
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/79464
Therefore, the GCF of Fractions 457/616,107/903 is 1/79464
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 616,903 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(616,903) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(616,903) x common factors =7 x 1 = 7
LCM(616,903) = ( 616 × 903 ) / 7
LCM(616,903) = 556248 / 7
LCM(616,903) = 79464
