Greatest Common Factor
We found the factors 83,93,21,603 . The biggest common factor number is the GCF number.
So the greatest common factor 83,93,21,603 is 1.
Lets's calculate LCM of 41,17,21,34
17 | 41, 17, 21, 34 |
41, 1, 21, 2 |
∴ So the LCM of the given numbers is 17 x 41 x 1 x 21 x 2 = 29274
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/29274
Therefore, the GCF of Fractions 83/41,93/17,21/21,603/34 is 1/29274
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 41,17,21,34 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(41,17,21,34) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(41,17,21,34) x common factors =1 x 17 = 17
LCM(41,17,21,34) = ( 41 × 17 × 21 × 34 ) / 17
LCM(41,17,21,34) = 497658 / 17
LCM(41,17,21,34) = 29274
