Given numbers are 280, 161, 256

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 161 are 7 x 23

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 280, 161, 256

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

Apply this formula for all numbers.

Step1:

LCM(280, 161) = 6440

GCD(280, 161) = ( 280 x 161 ) / 6440

= 280 / 161

= 280

Step2:

LCM(7, 256) = 1792

GCD(7, 256) = ( 7 x 256 ) / 1792

= 7 / 256

= 7

So, Greatest Common Divisor of 280, 161, 256 is 1
