Answer 1

Here, we need to find the largest number which divides 285 and 1249 leaving 9 and 7 as remainders. 

We subtract 9 and 7 from 285 and 1249.

= > 285 - 9

= > 276


= > 1249 - 7

= > 1242.


Now,

Find the HCF of 276 and 1242.

= > Prime factorization of 276 = 2 * 2 * 3 * 23

= > Prime factorization of 1242 = 2 * 3 * 3 * 3 * 23

HCF(276,1242) = 2 * 3 * 23

                          = 138.




Therefore the greatest number is 138.



Hope this helps!
