Given numbers are 665, 561, 403, 516

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 561 are 3 x 11 x 17

Prime factors of 403 are 13 x 31

Prime factors of 516 are 2 x 2 x 3 x 43

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

Given numbers are 665, 561, 403, 516

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

Apply this formula for all numbers.

Step1:

LCM(665, 561) = 373065

GCD(665, 561) = ( 665 x 561 ) / 373065

= 665 / 561

= 665

Step2:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

Step3:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

So, Greatest Common Divisor of 665, 561, 403, 516 is 1
