Given numbers are 640, 886, 657, 486

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 886 are 2 x 443

Prime factors of 657 are 3 x 3 x 73

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 640, 886, 657, 486

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

Apply this formula for all numbers.

Step1:

LCM(640, 886) = 283520

GCD(640, 886) = ( 640 x 886 ) / 283520

= 640 / 886

= 640

Step2:

LCM(2, 657) = 1314

GCD(2, 657) = ( 2 x 657 ) / 1314

= 2 / 657

= 2

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 640, 886, 657, 486 is 1
