Greatest Common Factor
We found the factors 28,49,857 . The biggest common factor number is the GCF number.
So the greatest common factor 28,49,857 is 1.
Lets's calculate LCM of 324,634,979
2 | 324, 634, 979 |
162, 317, 979 |
∴ So the LCM of the given numbers is 2 x 162 x 317 x 979 = 100551132
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/100551132
Therefore, the GCF of Fractions 28/324,49/634,857/979 is 1/100551132
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 324,634,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(324,634,979) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(324,634,979) x common factors =1 x 2 = 2
LCM(324,634,979) = ( 324 × 634 × 979 ) / 2
LCM(324,634,979) = 201102264 / 2
LCM(324,634,979) = 100551132
