So the greatest common factor 494,570 is 38.
Lets's calculate LCM of 748,605
11 | 748, 605 |
68, 55 |
∴ So the LCM of the given numbers is 11 x 68 x 55 = 41140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 38/41140
Therefore, the GCF of Fractions 494/748,570/605 is 38/41140
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 748,605 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(748,605) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(748,605) x common factors =11 x 1 = 11
LCM(748,605) = ( 748 × 605 ) / 11
LCM(748,605) = 452540 / 11
LCM(748,605) = 41140
