So the greatest common factor 645,5295 is 15.
Lets's calculate LCM of 671,854
61 | 671, 854 |
11, 14 |
∴ So the LCM of the given numbers is 61 x 11 x 14 = 9394
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/9394
Therefore, the GCF of Fractions 645/671,5295/854 is 15/9394
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 671,854 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(671,854) = 61
common factors(in case of two or more numbers have common factors) = 1
GCF(671,854) x common factors =61 x 1 = 61
LCM(671,854) = ( 671 × 854 ) / 61
LCM(671,854) = 573034 / 61
LCM(671,854) = 9394
