Given numbers are 430, 252, 538, 261

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 538 are 2 x 269

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 430, 252, 538, 261

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

Apply this formula for all numbers.

Step1:

LCM(430, 252) = 54180

GCD(430, 252) = ( 430 x 252 ) / 54180

= 430 / 252

= 430

Step2:

LCM(2, 538) = 538

GCD(2, 538) = ( 2 x 538 ) / 538

= 2 / 538

= 2

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 430, 252, 538, 261 is 1
