So the greatest common factor 311,612 is 1.
Lets's calculate LCM of 497,938
7 | 497, 938 |
71, 134 |
∴ So the LCM of the given numbers is 7 x 71 x 134 = 66598
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/66598
Therefore, the GCF of Fractions 311/497,612/938 is 1/66598
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 497,938 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(497,938) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(497,938) x common factors =7 x 1 = 7
LCM(497,938) = ( 497 × 938 ) / 7
LCM(497,938) = 466186 / 7
LCM(497,938) = 66598
