Given numbers are 180, 686, 529, 178

The list of prime factors of all numbers are

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 529 are 23 x 23

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 180, 686, 529, 178

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

Apply this formula for all numbers.

Step1:

LCM(180, 686) = 61740

GCD(180, 686) = ( 180 x 686 ) / 61740

= 180 / 686

= 180

Step2:

LCM(2, 529) = 1058

GCD(2, 529) = ( 2 x 529 ) / 1058

= 2 / 529

= 2

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 180, 686, 529, 178 is 1
