Lets's calculate LCM of 820,792
2 | 820, 792 |
2 | 410, 396 |
205, 198 |
∴ So the LCM of the given numbers is 2 x 2 x 205 x 198 = 162360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/162360
Therefore, the GCF of Fractions 986/820,921/792 is 1/162360
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 820,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,792) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(820,792) x common factors =4 x 1 = 4
LCM(820,792) = ( 820 × 792 ) / 4
LCM(820,792) = 649440 / 4
LCM(820,792) = 162360
