So the greatest common factor 320,256 is 64.
Lets's calculate LCM of 344,432
2 | 344, 432 |
2 | 172, 216 |
2 | 86, 108 |
43, 54 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 43 x 54 = 18576
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 64/18576
Therefore, the GCF of Fractions 320/344,256/432 is 64/18576
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 344,432 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(344,432) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(344,432) x common factors =8 x 1 = 8
LCM(344,432) = ( 344 × 432 ) / 8
LCM(344,432) = 148608 / 8
LCM(344,432) = 18576
