Question

Find the HCF of 1239\frac{12}{39}​ and 513\frac{5}{13}​.

A.

6013\frac{60}{13}​​

B.

6039\frac{60}{39}​​

C.

139\frac{1}{39}​​

D.

1213\frac{12}{13}​​

Correct option is C

Given:

HCF of 1239\frac{12}{39}​ and 513\frac{5}{13}​​

Concept Used:

HCF =HCF of numeratorsLCM of denominators \frac{\text{HCF of numerators}}{\text{LCM of denominators}}

Solution:

HCF =HCF(12,5)LCM(39,13) \frac{\text{HCF}(12, 5)}{\text{LCM}(39, 13)}

HCF(12, 5) = 1

LCM(39, 13) = 39 (since 13 divides 39)

HCF =139= \frac{1}{39}
