The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 927 are 3 x 3 x 103

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 690, 927, 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(690, 927) = 213210

GCD(690, 927) = ( 690 x 927 ) / 213210

= 690 / 927

= 690

Step2:

LCM(3, 972) = 972

GCD(3, 972) = ( 3 x 972 ) / 972

= 3 / 972

= 3

Step3:

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

= 3 / 845

= 3

So, Greatest Common Divisor of 690, 927, 972, 845 is 1
