Lets's calculate LCM of 644,427
7 | 644, 427 |
92, 61 |
∴ So the LCM of the given numbers is 7 x 92 x 61 = 39284
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 22/39284
Therefore, the GCF of Fractions 946/644,484/427 is 22/39284
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 644,427 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(644,427) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(644,427) x common factors =7 x 1 = 7
LCM(644,427) = ( 644 × 427 ) / 7
LCM(644,427) = 274988 / 7
LCM(644,427) = 39284
