So the greatest common factor 80,775,391 is 1.
Lets's calculate LCM of 435,388,728
2 | 435, 388, 728 |
2 | 435, 194, 364 |
435, 97, 182 |
∴ So the LCM of the given numbers is 2 x 2 x 435 x 97 x 182 = 30717960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30717960
Therefore, the GCF of Fractions 80/435,775/388,391/728 is 1/30717960
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 435,388,728 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(435,388,728) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(435,388,728) x common factors =1 x 4 = 4
LCM(435,388,728) = ( 435 × 388 × 728 ) / 4
LCM(435,388,728) = 122871840 / 4
LCM(435,388,728) = 30717960
