Lets's calculate GCF of 442,400
2 | 442, 400 |
221, 200 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 442
:1,2,13,17,26,34,221,442
Now, list down the factors of 400
:1,2,4,5,8,10,16,20,25,40,50,80,100,200,400
Greatest Common Factor
We found the factors 442,400 . The biggest common factor number is the GCF number.
So the greatest common factor 442,400 is 2.
Lets's calculate LCM of 102,406
2 | 102, 406 |
51, 203 |
∴ So the LCM of the given numbers is 2 x 51 x 203 = 20706
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/20706
Therefore, the GCF of Fractions 442/102,400/406 is 2/20706
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 102,406 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(102,406) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(102,406) x common factors =2 x 1 = 2
LCM(102,406) = ( 102 × 406 ) / 2
LCM(102,406) = 41412 / 2
LCM(102,406) = 20706
