Given numbers are 253, 217, 321, 434

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 217 are 7 x 31

Prime factors of 321 are 3 x 107

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 253, 217, 321, 434

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

Apply this formula for all numbers.

Step1:

LCM(253, 217) = 54901

GCD(253, 217) = ( 253 x 217 ) / 54901

= 253 / 217

= 253

Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 253, 217, 321, 434 is 1
