Given numbers are 640, 546, 792, 287

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 546 are 2 x 3 x 7 x 13

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 287 are 7 x 41

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

Given numbers are 640, 546, 792, 287

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

Apply this formula for all numbers.

Step1:

LCM(640, 546) = 174720

GCD(640, 546) = ( 640 x 546 ) / 174720

= 640 / 546

= 640

Step2:

LCM(2, 792) = 792

GCD(2, 792) = ( 2 x 792 ) / 792

= 2 / 792

= 2

Step3:

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

= 2 / 287

= 2

So, Greatest Common Divisor of 640, 546, 792, 287 is 1
