Greatest Common Factor
We found the factors 785,149 . The biggest common factor number is the GCF number.
So the greatest common factor 785,149 is 1.
Lets's calculate LCM of 280,286
2 | 280, 286 |
140, 143 |
∴ So the LCM of the given numbers is 2 x 140 x 143 = 40040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/40040
Therefore, the GCF of Fractions 785/280,149/286 is 1/40040
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 280,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(280,286) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(280,286) x common factors =2 x 1 = 2
LCM(280,286) = ( 280 × 286 ) / 2
LCM(280,286) = 80080 / 2
LCM(280,286) = 40040
