Greatest Common Factor
We found the factors 82,31,54,781 . The biggest common factor number is the GCF number.
So the greatest common factor 82,31,54,781 is 1.
Lets's calculate LCM of 80,92,35,69
2 | 80, 92, 35, 69 |
2 | 40, 46, 35, 69 |
5 | 20, 23, 35, 69 |
23 | 4, 23, 7, 69 |
4, 1, 7, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 23 x 4 x 1 x 7 x 3 = 38640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38640
Therefore, the GCF of Fractions 82/80,31/92,54/35,781/69 is 1/38640
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 80,92,35,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,92,35,69) = 1
common factors(in case of two or more numbers have common factors) = 460
GCF(80,92,35,69) x common factors =1 x 460 = 460
LCM(80,92,35,69) = ( 80 × 92 × 35 × 69 ) / 460
LCM(80,92,35,69) = 17774400 / 460
LCM(80,92,35,69) = 38640
