Answer 2

$here \: is \: your \: solution$

find the HCF of 65 and 117

using prime factorisation

117 = 1 × 65 + 52

65 = 1 × 52 + 13

52 = 4 ×13 + 0

Therefore HCF of (65 and 117) is 13.

65m -117 = 13

65m = 117+13

65m= 130

$m = \frac{130}{65} \\ m = 2$

Now

65 = 5 × 13

117 = 13 × 3 × 3

LCM of 65 and 117 = 5 × 13 × 3 × 3 = 585


Hope it helps you
