Given numbers are 195, 138, 286, 161

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

Apply this formula for all numbers.

Step1:

LCM(195, 138) = 8970

GCD(195, 138) = ( 195 x 138 ) / 8970

= 195 / 138

= 195

Step2:

LCM(3, 286) = 858

GCD(3, 286) = ( 3 x 286 ) / 858

= 3 / 286

= 3

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 195, 138, 286, 161 is 1
