Given numbers are 378, 747, 260, 556

The list of prime factors of all numbers are

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 747 are 3 x 3 x 83

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 378, 747, 260, 556

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

Apply this formula for all numbers.

Step1:

LCM(378, 747) = 31374

GCD(378, 747) = ( 378 x 747 ) / 31374

= 378 / 747

= 378

Step2:

LCM(9, 260) = 2340

GCD(9, 260) = ( 9 x 260 ) / 2340

= 9 / 260

= 9

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 378, 747, 260, 556 is 1
