Given numbers are 505, 620, 613, 869

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 613 are 613

Prime factors of 869 are 11 x 79

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

Given numbers are 505, 620, 613, 869

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

Apply this formula for all numbers.

Step1:

LCM(505, 620) = 62620

GCD(505, 620) = ( 505 x 620 ) / 62620

= 505 / 620

= 505

Step2:

LCM(5, 613) = 3065

GCD(5, 613) = ( 5 x 613 ) / 3065

= 5 / 613

= 5

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 505, 620, 613, 869 is 1
