The list of prime factors of all numbers are

Prime factors of 862 are 2 x 431

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 117 are 3 x 3 x 13

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

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

Given numbers are 862, 544, 117, 640

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

Apply this formula for all numbers.

Step1:

LCM(862, 544) = 234464

GCD(862, 544) = ( 862 x 544 ) / 234464

= 862 / 544

= 862

Step2:

LCM(2, 117) = 234

GCD(2, 117) = ( 2 x 117 ) / 234

= 2 / 117

= 2

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 862, 544, 117, 640 is 1
