Given numbers are 161, 259, 768, 400

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 259 are 7 x 37

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 161, 259, 768, 400

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

Apply this formula for all numbers.

Step1:

LCM(161, 259) = 5957

GCD(161, 259) = ( 161 x 259 ) / 5957

= 161 / 259

= 161

Step2:

LCM(7, 768) = 5376

GCD(7, 768) = ( 7 x 768 ) / 5376

= 7 / 768

= 7

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 161, 259, 768, 400 is 1
