So the greatest common factor 38,39,820 is 1.
Lets's calculate LCM of 677,632,618
2 | 677, 632, 618 |
677, 316, 309 |
∴ So the LCM of the given numbers is 2 x 677 x 316 x 309 = 132209976
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/132209976
Therefore, the GCF of Fractions 38/677,39/632,820/618 is 1/132209976
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 677,632,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(677,632,618) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(677,632,618) x common factors =1 x 2 = 2
LCM(677,632,618) = ( 677 × 632 × 618 ) / 2
LCM(677,632,618) = 264419952 / 2
LCM(677,632,618) = 132209976
