Lets's calculate GCF of 521,105
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 521
:1,521
Now, list down the factors of 105
:1,3,5,7,15,21,35,105
Greatest Common Factor
We found the factors 521,105 . The biggest common factor number is the GCF number.
So the greatest common factor 521,105 is 1.
Lets's calculate LCM of 481,820
Given numbers has no common factors except 1. So, there LCM is their product i.e 394420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/394420
Therefore, the GCF of Fractions 521/481,105/820 is 1/394420
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 481,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(481,820) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(481,820) x common factors =1 x 1 = 1
LCM(481,820) = ( 481 × 820 ) / 1
LCM(481,820) = 394420 / 1
LCM(481,820) = 394420
