So the greatest common factor 47,72,116 is 1.
Lets's calculate LCM of 98,30,649
2 | 98, 30, 649 |
49, 15, 649 |
∴ So the LCM of the given numbers is 2 x 49 x 15 x 649 = 954030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/954030
Therefore, the GCF of Fractions 47/98,72/30,116/649 is 1/954030
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 98,30,649 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,30,649) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(98,30,649) x common factors =1 x 2 = 2
LCM(98,30,649) = ( 98 × 30 × 649 ) / 2
LCM(98,30,649) = 1908060 / 2
LCM(98,30,649) = 954030
