Greatest Common Factor
We found the factors 673,400,717 . The biggest common factor number is the GCF number.
So the greatest common factor 673,400,717 is 1.
Lets's calculate LCM of 57,40,38
2 | 57, 40, 38 |
19 | 57, 20, 19 |
3, 20, 1 |
∴ So the LCM of the given numbers is 2 x 19 x 3 x 20 x 1 = 2280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2280
Therefore, the GCF of Fractions 673/57,400/40,717/38 is 1/2280
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 57,40,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,40,38) = 1
common factors(in case of two or more numbers have common factors) = 38
GCF(57,40,38) x common factors =1 x 38 = 38
LCM(57,40,38) = ( 57 × 40 × 38 ) / 38
LCM(57,40,38) = 86640 / 38
LCM(57,40,38) = 2280
