The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 791 are 7 x 113

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

Given numbers are 455, 570, 540, 791

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

Apply this formula for all numbers.

Step1:

LCM(455, 570) = 51870

GCD(455, 570) = ( 455 x 570 ) / 51870

= 455 / 570

= 455

Step2:

LCM(5, 540) = 540

GCD(5, 540) = ( 5 x 540 ) / 540

= 5 / 540

= 5

Step3:

LCM(5, 791) = 3955

GCD(5, 791) = ( 5 x 791 ) / 3955

= 5 / 791

= 5

So, Greatest Common Divisor of 455, 570, 540, 791 is 1
