Lets's calculate LCM of 285,6985
5 | 285, 6985 |
57, 1397 |
∴ So the LCM of the given numbers is 5 x 57 x 1397 = 398145
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/398145
Therefore, the GCF of Fractions 1985/285,6785/6985 is 5/398145
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 285,6985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(285,6985) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(285,6985) x common factors =5 x 1 = 5
LCM(285,6985) = ( 285 × 6985 ) / 5
LCM(285,6985) = 1990725 / 5
LCM(285,6985) = 398145
