1,2,4,5,10,11,20,22,44,55,110,220
Factors of 543
List of positive integer factors of 543 that divides 543 without a remainder.
1,3,181,543
Greatest Common Factor
We found the factors 471,220,543 . The biggest common factor number is the GCF number.
So the greatest common factor 471,220,543 is 1.
Lets's calculate LCM of 80,82,80
2 | 80, 82, 80 |
2 | 40, 41, 40 |
2 | 20, 41, 20 |
2 | 10, 41, 10 |
5 | 5, 41, 5 |
1, 41, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 41 x 1 = 3280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3280
Therefore, the GCF of Fractions 471/80,220/82,543/80 is 1/3280
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 80,82,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,82,80) = 2
common factors(in case of two or more numbers have common factors) = 80
GCF(80,82,80) x common factors =2 x 80 = 160
LCM(80,82,80) = ( 80 × 82 × 80 ) / 160
LCM(80,82,80) = 524800 / 160
LCM(80,82,80) = 3280
