Given numbers are 105, 616, 161

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(105, 616) = 9240

GCD(105, 616) = ( 105 x 616 ) / 9240

= 105 / 616

= 105

Step2:

LCM(7, 161) = 161

GCD(7, 161) = ( 7 x 161 ) / 161

= 7 / 161

= 7

So, Greatest Common Divisor of 105, 616, 161 is 7
