Question

the LCM of two numbers is 210 and their hcf is 14 .how many such pairs possible?

Answer 1

The answer to this question is 210x14

Answer 2

The two possible pairs are (14, 210) and (42, 70).

Step-by-step explanation:

The possible pairs could be find by using:

HCF ×  LCM = $N_{1}$ ×  $N_{2}$

(14 × 210) = $N_{1}$ ×  $N_{2}$

(14 ×  14 × 15) = $N_{1}$ ×  $N_{2}$

(14 ×  14 ×  (5 × 3) = $N_{1}$ ×  $N_{2}$

(3 ×  14) ×  (14 ×  5) = $N_{1}$ ×  $N_{2}$

Thus, the possible pairs are (14, 210) and (42, 70)
