Given numbers are 305, 556, 745, 763

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 556 are 2 x 2 x 139

Prime factors of 745 are 5 x 149

Prime factors of 763 are 7 x 109

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

Given numbers are 305, 556, 745, 763

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

Apply this formula for all numbers.

Step1:

LCM(305, 556) = 169580

GCD(305, 556) = ( 305 x 556 ) / 169580

= 305 / 556

= 305

Step2:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 305, 556, 745, 763 is 1
