1,89
Factors of 203
List of positive integer factors of 203 that divides 203 without a remainder.
1,7,29,203
Greatest Common Factor
We found the factors 56,89,203 . The biggest common factor number is the GCF number.
So the greatest common factor 56,89,203 is 1.
Lets's calculate LCM of 65,88,880
2 | 65, 88, 880 |
2 | 65, 44, 440 |
2 | 65, 22, 220 |
5 | 65, 11, 110 |
11 | 13, 11, 22 |
13, 1, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 11 x 13 x 1 x 2 = 11440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11440
Therefore, the GCF of Fractions 56/65,89/88,203/880 is 1/11440
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 65,88,880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,88,880) = 1
common factors(in case of two or more numbers have common factors) = 440
GCF(65,88,880) x common factors =1 x 440 = 440
LCM(65,88,880) = ( 65 × 88 × 880 ) / 440
LCM(65,88,880) = 5033600 / 440
LCM(65,88,880) = 11440
