Given numbers are 308, 530, 903, 705

The list of prime factors of all numbers are

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 530 are 2 x 5 x 53

Prime factors of 903 are 3 x 7 x 43

Prime factors of 705 are 3 x 5 x 47

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

Given numbers are 308, 530, 903, 705

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

Apply this formula for all numbers.

Step1:

LCM(308, 530) = 81620

GCD(308, 530) = ( 308 x 530 ) / 81620

= 308 / 530

= 308

Step2:

LCM(2, 903) = 1806

GCD(2, 903) = ( 2 x 903 ) / 1806

= 2 / 903

= 2

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 308, 530, 903, 705 is 1
