So the greatest common factor 28,68,22,12 is 2.
Lets's calculate LCM of 48,93,46,59
2 | 48, 93, 46, 59 |
3 | 24, 93, 23, 59 |
8, 31, 23, 59 |
∴ So the LCM of the given numbers is 2 x 3 x 8 x 31 x 23 x 59 = 2019216
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2019216
Therefore, the GCF of Fractions 28/48,68/93,22/46,12/59 is 2/2019216
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 48,93,46,59 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,93,46,59) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(48,93,46,59) x common factors =1 x 6 = 6
LCM(48,93,46,59) = ( 48 × 93 × 46 × 59 ) / 6
LCM(48,93,46,59) = 12115296 / 6
LCM(48,93,46,59) = 2019216
