So the greatest common factor 27,83,463 is 1.
Lets's calculate LCM of 638,396,456
2 | 638, 396, 456 |
2 | 319, 198, 228 |
3 | 319, 99, 114 |
11 | 319, 33, 38 |
29, 3, 38 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 11 x 29 x 3 x 38 = 436392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/436392
Therefore, the GCF of Fractions 27/638,83/396,463/456 is 1/436392
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 638,396,456 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,396,456) = 2
common factors(in case of two or more numbers have common factors) = 132
GCF(638,396,456) x common factors =2 x 132 = 264
LCM(638,396,456) = ( 638 × 396 × 456 ) / 264
LCM(638,396,456) = 115207488 / 264
LCM(638,396,456) = 436392
