1,2,31,41,62,82,1271,2542
Greatest Common Factor
We found the factors 390,2542 . The biggest common factor number is the GCF number.
So the greatest common factor 390,2542 is 2.
Lets's calculate LCM of 555,550
5 | 555, 550 |
111, 110 |
∴ So the LCM of the given numbers is 5 x 111 x 110 = 61050
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/61050
Therefore, the GCF of Fractions 390/555,2542/550 is 2/61050
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 555,550 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(555,550) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(555,550) x common factors =5 x 1 = 5
LCM(555,550) = ( 555 × 550 ) / 5
LCM(555,550) = 305250 / 5
LCM(555,550) = 61050
