Lets's calculate GCF of 122,488
2 | 122, 488 |
61 | 61, 244 |
1, 4 |
∴ So the GCF of the given numbers is 2 x 61 = 122
Now, list down the factors of 122
:1,2,61,122
Now, list down the factors of 488
:1,2,4,8,61,122,244,488
Greatest Common Factor
We found the factors 122,488 . The biggest common factor number is the GCF number.
So the greatest common factor 122,488 is 122.
Lets's calculate LCM of 978,132
2 | 978, 132 |
3 | 489, 66 |
163, 22 |
∴ So the LCM of the given numbers is 2 x 3 x 163 x 22 = 21516
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 122/21516
Therefore, the GCF of Fractions 122/978,488/132 is 122/21516
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 978,132 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(978,132) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(978,132) x common factors =6 x 1 = 6
LCM(978,132) = ( 978 × 132 ) / 6
LCM(978,132) = 129096 / 6
LCM(978,132) = 21516
