Given numbers are 180, 207, 772, 409

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 207 are 3 x 3 x 23

Prime factors of 772 are 2 x 2 x 193

Prime factors of 409 are 409

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

Given numbers are 180, 207, 772, 409

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

Apply this formula for all numbers.

Step1:

LCM(180, 207) = 4140

GCD(180, 207) = ( 180 x 207 ) / 4140

= 180 / 207

= 180

Step2:

LCM(9, 772) = 6948

GCD(9, 772) = ( 9 x 772 ) / 6948

= 9 / 772

= 9

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 180, 207, 772, 409 is 1
