Given numbers are 561, 855, 395, 488

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 395 are 5 x 79

Prime factors of 488 are 2 x 2 x 2 x 61

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

Given numbers are 561, 855, 395, 488

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

Apply this formula for all numbers.

Step1:

LCM(561, 855) = 159885

GCD(561, 855) = ( 561 x 855 ) / 159885

= 561 / 855

= 561

Step2:

LCM(3, 395) = 1185

GCD(3, 395) = ( 3 x 395 ) / 1185

= 3 / 395

= 3

Step3:

LCM(1, 488) = 488

GCD(1, 488) = ( 1 x 488 ) / 488

= 1 / 488

= 1

So, Greatest Common Divisor of 561, 855, 395, 488 is 1
