Greatest Common Factor
We found the factors 18,12,565 . The biggest common factor number is the GCF number.
So the greatest common factor 18,12,565 is 1.
Lets's calculate LCM of 298,544,502
2 | 298, 544, 502 |
149, 272, 251 |
∴ So the LCM of the given numbers is 2 x 149 x 272 x 251 = 20345056
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20345056
Therefore, the GCF of Fractions 18/298,12/544,565/502 is 1/20345056
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 298,544,502 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(298,544,502) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(298,544,502) x common factors =2 x 2 = 4
LCM(298,544,502) = ( 298 × 544 × 502 ) / 4
LCM(298,544,502) = 81380224 / 4
LCM(298,544,502) = 20345056
