So the greatest common factor 75,15,685 is 5.
Lets's calculate LCM of 306,428,360
2 | 306, 428, 360 |
2 | 153, 214, 180 |
3 | 153, 107, 90 |
3 | 51, 107, 30 |
17, 107, 10 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 17 x 107 x 10 = 654840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/654840
Therefore, the GCF of Fractions 75/306,15/428,685/360 is 5/654840
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 306,428,360 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(306,428,360) = 2
common factors(in case of two or more numbers have common factors) = 36
GCF(306,428,360) x common factors =2 x 36 = 72
LCM(306,428,360) = ( 306 × 428 × 360 ) / 72
LCM(306,428,360) = 47148480 / 72
LCM(306,428,360) = 654840
