Given numbers are 155, 318, 238, 203

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

Apply this formula for all numbers.

Step1:

LCM(155, 318) = 49290

GCD(155, 318) = ( 155 x 318 ) / 49290

= 155 / 318

= 155

Step2:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 155, 318, 238, 203 is 1
