So the greatest common factor 78,58,402 is 2.
Lets's calculate LCM of 436,410,328
2 | 436, 410, 328 |
2 | 218, 205, 164 |
41 | 109, 205, 82 |
109, 5, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 41 x 109 x 5 x 2 = 178760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/178760
Therefore, the GCF of Fractions 78/436,58/410,402/328 is 2/178760
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 436,410,328 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(436,410,328) = 2
common factors(in case of two or more numbers have common factors) = 164
GCF(436,410,328) x common factors =2 x 164 = 328
LCM(436,410,328) = ( 436 × 410 × 328 ) / 328
LCM(436,410,328) = 58633280 / 328
LCM(436,410,328) = 178760
