Given numbers are 203, 551, 91, 128

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

Apply this formula for all numbers.

Step1:

LCM(203, 551) = 3857

GCD(203, 551) = ( 203 x 551 ) / 3857

= 203 / 551

= 203

Step2:

LCM(29, 91) = 2639

GCD(29, 91) = ( 29 x 91 ) / 2639

= 29 / 91

= 29

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 203, 551, 91, 128 is 1
