Lets's calculate LCM of 639,369
3 | 639, 369 |
3 | 213, 123 |
71, 41 |
∴ So the LCM of the given numbers is 3 x 3 x 71 x 41 = 26199
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/26199
Therefore, the GCF of Fractions 648/639,9404/369 is 4/26199
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 639,369 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,369) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(639,369) x common factors =9 x 1 = 9
LCM(639,369) = ( 639 × 369 ) / 9
LCM(639,369) = 235791 / 9
LCM(639,369) = 26199
