Lets's calculate LCM of 684,456
2 | 684, 456 |
2 | 342, 228 |
3 | 171, 114 |
19 | 57, 38 |
3, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 19 x 3 x 2 = 1368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1368
Therefore, the GCF of Fractions 581/684,978/456 is 1/1368
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 684,456 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(684,456) = 228
common factors(in case of two or more numbers have common factors) = 1
GCF(684,456) x common factors =228 x 1 = 228
LCM(684,456) = ( 684 × 456 ) / 228
LCM(684,456) = 311904 / 228
LCM(684,456) = 1368
