So the greatest common factor 57,505,850 is 1.
Lets's calculate LCM of 435,315,731
3 | 435, 315, 731 |
5 | 145, 105, 731 |
29, 21, 731 |
∴ So the LCM of the given numbers is 3 x 5 x 29 x 21 x 731 = 6677685
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6677685
Therefore, the GCF of Fractions 57/435,505/315,850/731 is 1/6677685
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 435,315,731 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(435,315,731) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(435,315,731) x common factors =1 x 15 = 15
LCM(435,315,731) = ( 435 × 315 × 731 ) / 15
LCM(435,315,731) = 100165275 / 15
LCM(435,315,731) = 6677685
