So the greatest common factor 69,390,710 is 1.
Lets's calculate LCM of 652,397,430
2 | 652, 397, 430 |
326, 397, 215 |
∴ So the LCM of the given numbers is 2 x 326 x 397 x 215 = 55651460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/55651460
Therefore, the GCF of Fractions 69/652,390/397,710/430 is 1/55651460
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 652,397,430 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(652,397,430) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(652,397,430) x common factors =1 x 2 = 2
LCM(652,397,430) = ( 652 × 397 × 430 ) / 2
LCM(652,397,430) = 111302920 / 2
LCM(652,397,430) = 55651460
