The list of prime factors of all numbers are

Prime factors of 790 are 2 x 5 x 79

Prime factors of 278 are 2 x 139

Prime factors of 187 are 11 x 17

Prime factors of 505 are 5 x 101

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

Given numbers are 790, 278, 187, 505

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

Apply this formula for all numbers.

Step1:

LCM(790, 278) = 109810

GCD(790, 278) = ( 790 x 278 ) / 109810

= 790 / 278

= 790

Step2:

LCM(2, 187) = 374

GCD(2, 187) = ( 2 x 187 ) / 374

= 2 / 187

= 2

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 790, 278, 187, 505 is 1
