Greatest Common Factor
We found the factors 215,879 . The biggest common factor number is the GCF number.
So the greatest common factor 215,879 is 1.
Lets's calculate LCM of 255,710
5 | 255, 710 |
51, 142 |
∴ So the LCM of the given numbers is 5 x 51 x 142 = 36210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/36210
Therefore, the GCF of Fractions 215/255,879/710 is 1/36210
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 255,710 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(255,710) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(255,710) x common factors =5 x 1 = 5
LCM(255,710) = ( 255 × 710 ) / 5
LCM(255,710) = 181050 / 5
LCM(255,710) = 36210
