Given numbers are 623, 534, 855, 636

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 534 are 2 x 3 x 89

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

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 623, 534, 855, 636

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

Apply this formula for all numbers.

Step1:

LCM(623, 534) = 3738

GCD(623, 534) = ( 623 x 534 ) / 3738

= 623 / 534

= 623

Step2:

LCM(89, 855) = 76095

GCD(89, 855) = ( 89 x 855 ) / 76095

= 89 / 855

= 89

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 623, 534, 855, 636 is 1
