Given numbers are 258, 475, 641, 642

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 475 are 5 x 5 x 19

Prime factors of 641 are 641

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 258, 475, 641, 642

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

Apply this formula for all numbers.

Step1:

LCM(258, 475) = 122550

GCD(258, 475) = ( 258 x 475 ) / 122550

= 258 / 475

= 258

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 258, 475, 641, 642 is 1
