Given numbers are 665, 517, 447, 803

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 517 are 11 x 47

Prime factors of 447 are 3 x 149

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 665, 517, 447, 803

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

Apply this formula for all numbers.

Step1:

LCM(665, 517) = 343805

GCD(665, 517) = ( 665 x 517 ) / 343805

= 665 / 517

= 665

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 803) = 803

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

= 1 / 803

= 1

So, Greatest Common Divisor of 665, 517, 447, 803 is 1
