So the greatest common factor 818,816 is 2.
Lets's calculate LCM of 395,315
5 | 395, 315 |
79, 63 |
∴ So the LCM of the given numbers is 5 x 79 x 63 = 24885
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/24885
Therefore, the GCF of Fractions 818/395,816/315 is 2/24885
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 395,315 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(395,315) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(395,315) x common factors =5 x 1 = 5
LCM(395,315) = ( 395 × 315 ) / 5
LCM(395,315) = 124425 / 5
LCM(395,315) = 24885
