Question

H.C.F. of  1433, 2122, 4255\frac{14}{33},\ \frac{21}{22},\ \frac{42}{55}​  is:

A.

7330\frac{7}{330} \\​​

B.

42550 \frac{42}{550} \\​​

C.

3321 \frac{3}{321} \\​​

D.

21350\frac{21}{350}​​

Correct option is A

Given:
1433, 2122, 4255\frac{14}{33},\ \frac{21}{22},\ \frac{42}{55}​​
Formula:
H.C.F. of fractions =HCF of numeratorsLCM of denominators = \frac{\text{HCF of numerators}}{\text{LCM of denominators}} \\[5pt]​​
Numerators:  14, 21, 42=>HCF=714,\ 21,\ 42 \Rightarrow \text{HCF} = 7 \\​​
Denominators: 33, 22, 55=>LCM=330 33,\ 22,\ 55 \Rightarrow \text{LCM} = 330 \\[5pt]​​
So, HCF of given fractions =7330= \frac{7}{330}​​
Correct answer is 7330\frac{7}{330}​​
