Given numbers are 456, 184, 455, 391

The list of prime factors of all numbers are

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

Prime factors of 184 are 2 x 2 x 2 x 23

Prime factors of 455 are 5 x 7 x 13

Prime factors of 391 are 17 x 23

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

Given numbers are 456, 184, 455, 391

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

Apply this formula for all numbers.

Step1:

LCM(456, 184) = 10488

GCD(456, 184) = ( 456 x 184 ) / 10488

= 456 / 184

= 456

Step2:

LCM(8, 455) = 3640

GCD(8, 455) = ( 8 x 455 ) / 3640

= 8 / 455

= 8

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 456, 184, 455, 391 is 1
