So the greatest common factor 431,297,570 is 1.
Lets's calculate LCM of 513,249,680
3 | 513, 249, 680 |
171, 83, 680 |
∴ So the LCM of the given numbers is 3 x 171 x 83 x 680 = 28953720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28953720
Therefore, the GCF of Fractions 431/513,297/249,570/680 is 1/28953720
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 513,249,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(513,249,680) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(513,249,680) x common factors =1 x 3 = 3
LCM(513,249,680) = ( 513 × 249 × 680 ) / 3
LCM(513,249,680) = 86861160 / 3
LCM(513,249,680) = 28953720
