The list of prime factors of all numbers are

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 395 are 5 x 79

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 972, 768, 395, 245

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

Apply this formula for all numbers.

Step1:

LCM(972, 768) = 62208

GCD(972, 768) = ( 972 x 768 ) / 62208

= 972 / 768

= 972

Step2:

LCM(12, 395) = 4740

GCD(12, 395) = ( 12 x 395 ) / 4740

= 12 / 395

= 12

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 972, 768, 395, 245 is 1
