Lets's calculate LCM of 260,858
2 | 260, 858 |
13 | 130, 429 |
10, 33 |
∴ So the LCM of the given numbers is 2 x 13 x 10 x 33 = 8580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/8580
Therefore, the GCF of Fractions 117/260,143/858 is 13/8580
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 260,858 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(260,858) = 26
common factors(in case of two or more numbers have common factors) = 1
GCF(260,858) x common factors =26 x 1 = 26
LCM(260,858) = ( 260 × 858 ) / 26
LCM(260,858) = 223080 / 26
LCM(260,858) = 8580
