Lets's calculate LCM of 165,861
3 | 165, 861 |
55, 287 |
∴ So the LCM of the given numbers is 3 x 55 x 287 = 47355
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/47355
Therefore, the GCF of Fractions 623/165,4238/861 is 1/47355
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 165,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(165,861) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(165,861) x common factors =3 x 1 = 3
LCM(165,861) = ( 165 × 861 ) / 3
LCM(165,861) = 142065 / 3
LCM(165,861) = 47355
