So the greatest common factor 306,504 is 18.
Lets's calculate LCM of 28,6702
2 | 28, 6702 |
14, 3351 |
∴ So the LCM of the given numbers is 2 x 14 x 3351 = 93828
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/93828
Therefore, the GCF of Fractions 306/28,504/6702 is 18/93828
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 28,6702 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,6702) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(28,6702) x common factors =2 x 1 = 2
LCM(28,6702) = ( 28 × 6702 ) / 2
LCM(28,6702) = 187656 / 2
LCM(28,6702) = 93828
