The factors of 231 are 1, 3, 7, 11, 21, 33, 77, 231
The HCF of 483,231 is 21.
Lets's calculate GCF of 483,231
3 | 483, 231 |
7 | 161, 77 |
23, 11 |
∴ So the GCF of the given numbers is 3 x 7 = 21
Now, list down the factors of 483
:1,3,7,21,23,69,161,483
Now, list down the factors of 231
:1,3,7,11,21,33,77,231
Greatest Common Factor
We found the factors 483,231 . The biggest common factor number is the GCF number.
So the greatest common factor 483,231 is 21.
Lets's calculate LCM of 105,310
5 | 105, 310 |
21, 62 |
∴ So the LCM of the given numbers is 5 x 21 x 62 = 6510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/6510
Therefore, the GCF of Fractions 483/105,231/310 is 21/6510
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 105,310 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(105,310) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(105,310) x common factors =5 x 1 = 5
LCM(105,310) = ( 105 × 310 ) / 5
LCM(105,310) = 32550 / 5
LCM(105,310) = 6510
