So the greatest common factor 677,309 is 1.
Lets's calculate LCM of 990,158
2 | 990, 158 |
495, 79 |
∴ So the LCM of the given numbers is 2 x 495 x 79 = 78210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/78210
Therefore, the GCF of Fractions 677/990,309/158 is 1/78210
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 990,158 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(990,158) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(990,158) x common factors =2 x 1 = 2
LCM(990,158) = ( 990 × 158 ) / 2
LCM(990,158) = 156420 / 2
LCM(990,158) = 78210
