The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 634 are 2 x 317

Prime factors of 523 are 523

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 505, 634, 523, 920

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

Apply this formula for all numbers.

Step1:

LCM(505, 634) = 320170

GCD(505, 634) = ( 505 x 634 ) / 320170

= 505 / 634

= 505

Step2:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 505, 634, 523, 920 is 1
