Given numbers are 728, 943, 130, 178

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 943 are 23 x 41

Prime factors of 130 are 2 x 5 x 13

Prime factors of 178 are 2 x 89

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

Given numbers are 728, 943, 130, 178

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

Apply this formula for all numbers.

Step1:

LCM(728, 943) = 686504

GCD(728, 943) = ( 728 x 943 ) / 686504

= 728 / 943

= 728

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 728, 943, 130, 178 is 1
