Given numbers are 521, 232, 580, 642

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 232 are 2 x 2 x 2 x 29

Prime factors of 580 are 2 x 2 x 5 x 29

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 521, 232, 580, 642

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

Apply this formula for all numbers.

Step1:

LCM(521, 232) = 120872

GCD(521, 232) = ( 521 x 232 ) / 120872

= 521 / 232

= 521

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 642) = 642

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

= 1 / 642

= 1

So, Greatest Common Divisor of 521, 232, 580, 642 is 1
