Lets's calculate LCM of 891,207
3 | 891, 207 |
3 | 297, 69 |
99, 23 |
∴ So the LCM of the given numbers is 3 x 3 x 99 x 23 = 20493
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/20493
Therefore, the GCF of Fractions 346/891,620/207 is 2/20493
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 891,207 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(891,207) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(891,207) x common factors =9 x 1 = 9
LCM(891,207) = ( 891 × 207 ) / 9
LCM(891,207) = 184437 / 9
LCM(891,207) = 20493
