Given numbers are 221, 456, 178, 319

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 178 are 2 x 89

Prime factors of 319 are 11 x 29

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

Given numbers are 221, 456, 178, 319

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

Apply this formula for all numbers.

Step1:

LCM(221, 456) = 100776

GCD(221, 456) = ( 221 x 456 ) / 100776

= 221 / 456

= 221

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

Step3:

LCM(1, 319) = 319

GCD(1, 319) = ( 1 x 319 ) / 319

= 1 / 319

= 1

So, Greatest Common Divisor of 221, 456, 178, 319 is 1
