So the greatest common factor 816,855 is 3.
Lets's calculate LCM of 418,360
2 | 418, 360 |
209, 180 |
∴ So the LCM of the given numbers is 2 x 209 x 180 = 75240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/75240
Therefore, the GCF of Fractions 816/418,855/360 is 3/75240
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 418,360 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(418,360) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(418,360) x common factors =2 x 1 = 2
LCM(418,360) = ( 418 × 360 ) / 2
LCM(418,360) = 150480 / 2
LCM(418,360) = 75240
