So the greatest common factor 239,332,985 is 1.
Lets's calculate LCM of 17,81,78
3 | 17, 81, 78 |
17, 27, 26 |
∴ So the LCM of the given numbers is 3 x 17 x 27 x 26 = 35802
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/35802
Therefore, the GCF of Fractions 239/17,332/81,985/78 is 1/35802
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 17,81,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,81,78) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(17,81,78) x common factors =1 x 3 = 3
LCM(17,81,78) = ( 17 × 81 × 78 ) / 3
LCM(17,81,78) = 107406 / 3
LCM(17,81,78) = 35802
