Given numbers are 280, 825, 163, 356

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 163 are 163

Prime factors of 356 are 2 x 2 x 89

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

Given numbers are 280, 825, 163, 356

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

Apply this formula for all numbers.

Step1:

LCM(280, 825) = 46200

GCD(280, 825) = ( 280 x 825 ) / 46200

= 280 / 825

= 280

Step2:

LCM(5, 163) = 815

GCD(5, 163) = ( 5 x 163 ) / 815

= 5 / 163

= 5

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 280, 825, 163, 356 is 1
