Greatest Common Factor
We found the factors 758,781 . The biggest common factor number is the GCF number.
So the greatest common factor 758,781 is 1.
Lets's calculate LCM of 40,422
2 | 40, 422 |
20, 211 |
∴ So the LCM of the given numbers is 2 x 20 x 211 = 8440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8440
Therefore, the GCF of Fractions 758/40,781/422 is 1/8440
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 40,422 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,422) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(40,422) x common factors =2 x 1 = 2
LCM(40,422) = ( 40 × 422 ) / 2
LCM(40,422) = 16880 / 2
LCM(40,422) = 8440
