Your question is easy but in board exam the question must be asked as 65m - 117n .

By Using Euclid's division lemma,

a = bq +r

Clearly 117>65.

117 = 65 × 1 + 52 →→ [ 2 ]

65 = 52 x 1 + 13 →→ [1]

52 = 13 x 4 + 0

HCF = 13


According to question →→→

13 = 65m + 117n


From [ 1] ,
13 = 65 - 52 x 1

From [2] ,
52 = 117 - 65 x 1 →→ [3]

Hence ,

13 = 65 - [ 117 - 65 x 1 ] →→ from [3]

= 65 x 2 - 117

= 65 x 2 + 117 x [-1 ]

m = 2
n = -1

Hope this help us .

Keep it up.
