So the greatest common factor 939,142 is 1.
Lets's calculate LCM of 78,771
3 | 78, 771 |
26, 257 |
∴ So the LCM of the given numbers is 3 x 26 x 257 = 20046
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20046
Therefore, the GCF of Fractions 939/78,142/771 is 1/20046
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 78,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,771) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(78,771) x common factors =3 x 1 = 3
LCM(78,771) = ( 78 × 771 ) / 3
LCM(78,771) = 60138 / 3
LCM(78,771) = 20046
