So the greatest common factor 77,22 is 11.
Lets's calculate LCM of 810,3622
2 | 810, 3622 |
405, 1811 |
∴ So the LCM of the given numbers is 2 x 405 x 1811 = 1466910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/1466910
Therefore, the GCF of Fractions 77/810,22/3622 is 11/1466910
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 810,3622 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,3622) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(810,3622) x common factors =2 x 1 = 2
LCM(810,3622) = ( 810 × 3622 ) / 2
LCM(810,3622) = 2933820 / 2
LCM(810,3622) = 1466910
