Given numbers are 155, 169, 361, 158

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

Apply this formula for all numbers.

Step1:

LCM(155, 169) = 26195

GCD(155, 169) = ( 155 x 169 ) / 26195

= 155 / 169

= 155

Step2:

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

= 1 / 361

= 1

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 155, 169, 361, 158 is 1
