So the greatest common factor 32,862,378 is 2.
Lets's calculate LCM of 30,98,320
2 | 30, 98, 320 |
5 | 15, 49, 160 |
3, 49, 32 |
∴ So the LCM of the given numbers is 2 x 5 x 3 x 49 x 32 = 47040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/47040
Therefore, the GCF of Fractions 32/30,862/98,378/320 is 2/47040
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 30,98,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,98,320) = 2
common factors(in case of two or more numbers have common factors) = 10
GCF(30,98,320) x common factors =2 x 10 = 20
LCM(30,98,320) = ( 30 × 98 × 320 ) / 20
LCM(30,98,320) = 940800 / 20
LCM(30,98,320) = 47040
