Given numbers are 665, 611, 689, 808

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 611 are 13 x 47

Prime factors of 689 are 13 x 53

Prime factors of 808 are 2 x 2 x 2 x 101

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

Given numbers are 665, 611, 689, 808

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

Apply this formula for all numbers.

Step1:

LCM(665, 611) = 406315

GCD(665, 611) = ( 665 x 611 ) / 406315

= 665 / 611

= 665

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 665, 611, 689, 808 is 1
