Given numbers are 561, 828, 899, 427

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

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

Prime factors of 899 are 29 x 31

Prime factors of 427 are 7 x 61

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

Given numbers are 561, 828, 899, 427

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

Apply this formula for all numbers.

Step1:

LCM(561, 828) = 154836

GCD(561, 828) = ( 561 x 828 ) / 154836

= 561 / 828

= 561

Step2:

LCM(3, 899) = 2697

GCD(3, 899) = ( 3 x 899 ) / 2697

= 3 / 899

= 3

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 561, 828, 899, 427 is 1
