Lets's calculate LCM of 45,8585
5 | 45, 8585 |
9, 1717 |
∴ So the LCM of the given numbers is 5 x 9 x 1717 = 77265
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/77265
Therefore, the GCF of Fractions 777/45,549/8585 is 3/77265
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 45,8585 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,8585) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(45,8585) x common factors =5 x 1 = 5
LCM(45,8585) = ( 45 × 8585 ) / 5
LCM(45,8585) = 386325 / 5
LCM(45,8585) = 77265
