The list of prime factors of all numbers are

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 989 are 23 x 43

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 728, 492, 989, 231

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

Apply this formula for all numbers.

Step1:

LCM(728, 492) = 89544

GCD(728, 492) = ( 728 x 492 ) / 89544

= 728 / 492

= 728

Step2:

LCM(4, 989) = 3956

GCD(4, 989) = ( 4 x 989 ) / 3956

= 4 / 989

= 4

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 728, 492, 989, 231 is 1
