We found the factors 987,249 . The biggest common factor number is the GCF number.
So the greatest common factor 987,249 is 3.
Lets's calculate LCM of 174,512
2 | 174, 512 |
87, 256 |
∴ So the LCM of the given numbers is 2 x 87 x 256 = 44544
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/44544
Therefore, the GCF of Fractions 987/174,249/512 is 3/44544
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 174,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(174,512) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(174,512) x common factors =2 x 1 = 2
LCM(174,512) = ( 174 × 512 ) / 2
LCM(174,512) = 89088 / 2
LCM(174,512) = 44544
