Given numbers are 254, 122, 972, 845

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 122 are 2 x 61

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

Prime factors of 845 are 5 x 13 x 13

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

Given numbers are 254, 122, 972, 845

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

Apply this formula for all numbers.

Step1:

LCM(254, 122) = 15494

GCD(254, 122) = ( 254 x 122 ) / 15494

= 254 / 122

= 254

Step2:

LCM(2, 972) = 972

GCD(2, 972) = ( 2 x 972 ) / 972

= 2 / 972

= 2

Step3:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

So, Greatest Common Divisor of 254, 122, 972, 845 is 1
