Given numbers are 658, 517, 445, 207

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 517 are 11 x 47

Prime factors of 445 are 5 x 89

Prime factors of 207 are 3 x 3 x 23

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

Given numbers are 658, 517, 445, 207

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

Apply this formula for all numbers.

Step1:

LCM(658, 517) = 7238

GCD(658, 517) = ( 658 x 517 ) / 7238

= 658 / 517

= 658

Step2:

LCM(47, 445) = 20915

GCD(47, 445) = ( 47 x 445 ) / 20915

= 47 / 445

= 47

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 658, 517, 445, 207 is 1
