Lets's calculate LCM of 484,572
2 | 484, 572 |
2 | 242, 286 |
11 | 121, 143 |
11, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 11 x 11 x 13 = 6292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6292
Therefore, the GCF of Fractions 477/484,390/572 is 3/6292
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 484,572 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(484,572) = 44
common factors(in case of two or more numbers have common factors) = 1
GCF(484,572) x common factors =44 x 1 = 44
LCM(484,572) = ( 484 × 572 ) / 44
LCM(484,572) = 276848 / 44
LCM(484,572) = 6292
