Lets's calculate LCM of 158,328
2 | 158, 328 |
79, 164 |
∴ So the LCM of the given numbers is 2 x 79 x 164 = 25912
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/25912
Therefore, the GCF of Fractions 489/158,957/328 is 3/25912
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 158,328 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(158,328) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(158,328) x common factors =2 x 1 = 2
LCM(158,328) = ( 158 × 328 ) / 2
LCM(158,328) = 51824 / 2
LCM(158,328) = 25912
