Lets's calculate LCM of 620,685
5 | 620, 685 |
124, 137 |
∴ So the LCM of the given numbers is 5 x 124 x 137 = 84940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/84940
Therefore, the GCF of Fractions 659/620,608/685 is 1/84940
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 620,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,685) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(620,685) x common factors =5 x 1 = 5
LCM(620,685) = ( 620 × 685 ) / 5
LCM(620,685) = 424700 / 5
LCM(620,685) = 84940
