Given numbers are 641, 664, 806, 288

The list of prime factors of all numbers are

Prime factors of 641 are 641

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 806 are 2 x 13 x 31

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 641, 664, 806, 288

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

Apply this formula for all numbers.

Step1:

LCM(641, 664) = 425624

GCD(641, 664) = ( 641 x 664 ) / 425624

= 641 / 664

= 641

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

Step3:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

So, Greatest Common Divisor of 641, 664, 806, 288 is 1
