Given numbers are 171, 257, 635, 603

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

Apply this formula for all numbers.

Step1:

LCM(171, 257) = 43947

GCD(171, 257) = ( 171 x 257 ) / 43947

= 171 / 257

= 171

Step2:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 171, 257, 635, 603 is 1
