Given numbers are 161, 353, 256, 783

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 353 are 353

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

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 161, 353, 256, 783

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

Apply this formula for all numbers.

Step1:

LCM(161, 353) = 56833

GCD(161, 353) = ( 161 x 353 ) / 56833

= 161 / 353

= 161

Step2:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 161, 353, 256, 783 is 1
