So the greatest common factor 787,317 is 1.
Lets's calculate LCM of 685,160
5 | 685, 160 |
137, 32 |
∴ So the LCM of the given numbers is 5 x 137 x 32 = 21920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21920
Therefore, the GCF of Fractions 787/685,317/160 is 1/21920
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 685,160 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,160) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(685,160) x common factors =5 x 1 = 5
LCM(685,160) = ( 685 × 160 ) / 5
LCM(685,160) = 109600 / 5
LCM(685,160) = 21920
