So the greatest common factor 867,432 is 3.
Lets's calculate LCM of 435,423
3 | 435, 423 |
145, 141 |
∴ So the LCM of the given numbers is 3 x 145 x 141 = 61335
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/61335
Therefore, the GCF of Fractions 867/435,432/423 is 3/61335
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 435,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(435,423) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(435,423) x common factors =3 x 1 = 3
LCM(435,423) = ( 435 × 423 ) / 3
LCM(435,423) = 184005 / 3
LCM(435,423) = 61335
