Given numbers are 663, 655, 324, 803

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 655 are 5 x 131

Prime factors of 324 are 2 x 2 x 3 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 663, 655, 324, 803

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

Apply this formula for all numbers.

Step1:

LCM(663, 655) = 434265

GCD(663, 655) = ( 663 x 655 ) / 434265

= 663 / 655

= 663

Step2:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

Step3:

LCM(1, 803) = 803

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

= 1 / 803

= 1

So, Greatest Common Divisor of 663, 655, 324, 803 is 1
