So the greatest common factor 54,207,490 is 1.
Lets's calculate LCM of 785,985,361
5 | 785, 985, 361 |
157, 197, 361 |
∴ So the LCM of the given numbers is 5 x 157 x 197 x 361 = 55826845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/55826845
Therefore, the GCF of Fractions 54/785,207/985,490/361 is 1/55826845
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 785,985,361 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(785,985,361) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(785,985,361) x common factors =1 x 5 = 5
LCM(785,985,361) = ( 785 × 985 × 361 ) / 5
LCM(785,985,361) = 279134225 / 5
LCM(785,985,361) = 55826845
