The list of prime factors of all numbers are

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 477 are 3 x 3 x 53

Prime factors of 938 are 2 x 7 x 67

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 495, 477, 938, 640

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

Apply this formula for all numbers.

Step1:

LCM(495, 477) = 26235

GCD(495, 477) = ( 495 x 477 ) / 26235

= 495 / 477

= 495

Step2:

LCM(9, 938) = 8442

GCD(9, 938) = ( 9 x 938 ) / 8442

= 9 / 938

= 9

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 495, 477, 938, 640 is 1
