So the greatest common factor 308,220 is 44.
Lets's calculate LCM of 484,230
2 | 484, 230 |
242, 115 |
∴ So the LCM of the given numbers is 2 x 242 x 115 = 55660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 44/55660
Therefore, the GCF of Fractions 308/484,220/230 is 44/55660
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 484,230 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(484,230) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(484,230) x common factors =2 x 1 = 2
LCM(484,230) = ( 484 × 230 ) / 2
LCM(484,230) = 111320 / 2
LCM(484,230) = 55660
