Given numbers are 642, 483, 258, 253

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 483 are 3 x 7 x 23

Prime factors of 258 are 2 x 3 x 43

Prime factors of 253 are 11 x 23

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

Given numbers are 642, 483, 258, 253

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

Apply this formula for all numbers.

Step1:

LCM(642, 483) = 103362

GCD(642, 483) = ( 642 x 483 ) / 103362

= 642 / 483

= 642

Step2:

LCM(3, 258) = 258

GCD(3, 258) = ( 3 x 258 ) / 258

= 3 / 258

= 3

Step3:

LCM(3, 253) = 759

GCD(3, 253) = ( 3 x 253 ) / 759

= 3 / 253

= 3

So, Greatest Common Divisor of 642, 483, 258, 253 is 1
