So the greatest common factor 728,455 is 91.
Lets's calculate LCM of 174,686
2 | 174, 686 |
87, 343 |
∴ So the LCM of the given numbers is 2 x 87 x 343 = 59682
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 91/59682
Therefore, the GCF of Fractions 728/174,455/686 is 91/59682
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 174,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(174,686) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(174,686) x common factors =2 x 1 = 2
LCM(174,686) = ( 174 × 686 ) / 2
LCM(174,686) = 119364 / 2
LCM(174,686) = 59682
