Lets's calculate LCM of 372,155
| 31 | 372, 155 |
| 12, 5 |
∴ So the LCM of the given numbers is 31 x 12 x 5 = 1860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/1860
Therefore, the GCF of Fractions 448/372,3948/155 is 28/1860
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 372,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(372,155) = 31
common factors(in case of two or more numbers have common factors) = 1
GCF(372,155) x common factors =31 x 1 = 31
LCM(372,155) = ( 372 × 155 ) / 31
LCM(372,155) = 57660 / 31
LCM(372,155) = 1860
