So the greatest common factor 424,326,784 is 2.
Lets's calculate LCM of 20,71,315
5 | 20, 71, 315 |
4, 71, 63 |
∴ So the LCM of the given numbers is 5 x 4 x 71 x 63 = 89460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/89460
Therefore, the GCF of Fractions 424/20,326/71,784/315 is 2/89460
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 20,71,315 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,71,315) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(20,71,315) x common factors =1 x 5 = 5
LCM(20,71,315) = ( 20 × 71 × 315 ) / 5
LCM(20,71,315) = 447300 / 5
LCM(20,71,315) = 89460
