Given numbers are 640, 602, 806, 847

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 602 are 2 x 7 x 43

Prime factors of 806 are 2 x 13 x 31

Prime factors of 847 are 7 x 11 x 11

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

Given numbers are 640, 602, 806, 847

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

Apply this formula for all numbers.

Step1:

LCM(640, 602) = 192640

GCD(640, 602) = ( 640 x 602 ) / 192640

= 640 / 602

= 640

Step2:

LCM(2, 806) = 806

GCD(2, 806) = ( 2 x 806 ) / 806

= 2 / 806

= 2

Step3:

LCM(2, 847) = 1694

GCD(2, 847) = ( 2 x 847 ) / 1694

= 2 / 847

= 2

So, Greatest Common Divisor of 640, 602, 806, 847 is 1
