The factors of 821 are 1, 821
The HCF of 220,821 is 1.
Lets's calculate GCF of 220,821
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 220
:1,2,4,5,10,11,20,22,44,55,110,220
Now, list down the factors of 821
:1,821
Greatest Common Factor
We found the factors 220,821 . The biggest common factor number is the GCF number.
So the greatest common factor 220,821 is 1.
Lets's calculate LCM of 65,345
5 | 65, 345 |
13, 69 |
∴ So the LCM of the given numbers is 5 x 13 x 69 = 4485
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4485
Therefore, the GCF of Fractions 220/65,821/345 is 1/4485
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 65,345 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,345) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(65,345) x common factors =5 x 1 = 5
LCM(65,345) = ( 65 × 345 ) / 5
LCM(65,345) = 22425 / 5
LCM(65,345) = 4485
