Given numbers are 685, 207, 432, 803

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 207 are 3 x 3 x 23

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 803 are 11 x 73

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

Given numbers are 685, 207, 432, 803

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

Apply this formula for all numbers.

Step1:

LCM(685, 207) = 141795

GCD(685, 207) = ( 685 x 207 ) / 141795

= 685 / 207

= 685

Step2:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 685, 207, 432, 803 is 1
