Lets's calculate GCF of 378,847
7 | 378, 847 |
54, 121 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 378
:1,2,3,6,7,9,14,18,21,27,42,54,63,126,189,378
Now, list down the factors of 847
:1,7,11,77,121,847
Greatest Common Factor
We found the factors 378,847 . The biggest common factor number is the GCF number.
So the greatest common factor 378,847 is 7.
Lets's calculate LCM of 16,122
2 | 16, 122 |
8, 61 |
∴ So the LCM of the given numbers is 2 x 8 x 61 = 976
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/976
Therefore, the GCF of Fractions 378/16,847/122 is 7/976
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 16,122 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,122) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(16,122) x common factors =2 x 1 = 2
LCM(16,122) = ( 16 × 122 ) / 2
LCM(16,122) = 1952 / 2
LCM(16,122) = 976
