∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 721
:1,7,103,721
Now, list down the factors of 800
:1,2,4,5,8,10,16,20,25,32,40,50,80,100,160,200,400,800
Greatest Common Factor
We found the factors 721,800 . The biggest common factor number is the GCF number.
So the greatest common factor 721,800 is 1.
Lets's calculate LCM of 914,820
2 | 914, 820 |
457, 410 |
∴ So the LCM of the given numbers is 2 x 457 x 410 = 374740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/374740
Therefore, the GCF of Fractions 721/914,800/820 is 1/374740
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 914,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(914,820) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(914,820) x common factors =2 x 1 = 2
LCM(914,820) = ( 914 × 820 ) / 2
LCM(914,820) = 749480 / 2
LCM(914,820) = 374740
