Given numbers are 203, 305, 357, 437

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 305 are 5 x 61

Prime factors of 357 are 3 x 7 x 17

Prime factors of 437 are 19 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 203, 305, 357, 437

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

Apply this formula for all numbers.

Step1:

LCM(203, 305) = 61915

GCD(203, 305) = ( 203 x 305 ) / 61915

= 203 / 305

= 203

Step2:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 203, 305, 357, 437 is 1
