Given numbers are 640, 805, 394, 854

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 805 are 5 x 7 x 23

Prime factors of 394 are 2 x 197

Prime factors of 854 are 2 x 7 x 61

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

Given numbers are 640, 805, 394, 854

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

Apply this formula for all numbers.

Step1:

LCM(640, 805) = 103040

GCD(640, 805) = ( 640 x 805 ) / 103040

= 640 / 805

= 640

Step2:

LCM(5, 394) = 1970

GCD(5, 394) = ( 5 x 394 ) / 1970

= 5 / 394

= 5

Step3:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

So, Greatest Common Divisor of 640, 805, 394, 854 is 1
