Lets's calculate LCM of 345,885
3 | 345, 885 |
5 | 115, 295 |
23, 59 |
∴ So the LCM of the given numbers is 3 x 5 x 23 x 59 = 20355
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20355
Therefore, the GCF of Fractions 971/345,986/885 is 1/20355
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 345,885 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(345,885) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(345,885) x common factors =15 x 1 = 15
LCM(345,885) = ( 345 × 885 ) / 15
LCM(345,885) = 305325 / 15
LCM(345,885) = 20355
