Given numbers are 405, 623, 828, 524

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 623 are 7 x 89

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 524 are 2 x 2 x 131

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

Given numbers are 405, 623, 828, 524

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

Apply this formula for all numbers.

Step1:

LCM(405, 623) = 252315

GCD(405, 623) = ( 405 x 623 ) / 252315

= 405 / 623

= 405

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 524) = 524

GCD(1, 524) = ( 1 x 524 ) / 524

= 1 / 524

= 1

So, Greatest Common Divisor of 405, 623, 828, 524 is 1
