Given numbers are 408, 861, 528, 797

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 861 are 3 x 7 x 41

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 797 are 797

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

Given numbers are 408, 861, 528, 797

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

Apply this formula for all numbers.

Step1:

LCM(408, 861) = 117096

GCD(408, 861) = ( 408 x 861 ) / 117096

= 408 / 861

= 408

Step2:

LCM(3, 528) = 528

GCD(3, 528) = ( 3 x 528 ) / 528

= 3 / 528

= 3

Step3:

LCM(3, 797) = 2391

GCD(3, 797) = ( 3 x 797 ) / 2391

= 3 / 797

= 3

So, Greatest Common Divisor of 408, 861, 528, 797 is 1
