Given numbers are 161, 287, 181, 195

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

Apply this formula for all numbers.

Step1:

LCM(161, 287) = 6601

GCD(161, 287) = ( 161 x 287 ) / 6601

= 161 / 287

= 161

Step2:

LCM(7, 181) = 1267

GCD(7, 181) = ( 7 x 181 ) / 1267

= 7 / 181

= 7

Step3:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 161, 287, 181, 195 is 1
