So the greatest common factor 30,93,642 is 3.
Lets's calculate LCM of 489,652,208
2 | 489, 652, 208 |
2 | 489, 326, 104 |
163 | 489, 163, 52 |
3, 1, 52 |
∴ So the LCM of the given numbers is 2 x 2 x 163 x 3 x 1 x 52 = 101712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/101712
Therefore, the GCF of Fractions 30/489,93/652,642/208 is 3/101712
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 489,652,208 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(489,652,208) = 1
common factors(in case of two or more numbers have common factors) = 652
GCF(489,652,208) x common factors =1 x 652 = 652
LCM(489,652,208) = ( 489 × 652 × 208 ) / 652
LCM(489,652,208) = 66316224 / 652
LCM(489,652,208) = 101712
