The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 455 are 5 x 7 x 13

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

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

Given numbers are 672, 424, 455, 162

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

Apply this formula for all numbers.

Step1:

LCM(672, 424) = 35616

GCD(672, 424) = ( 672 x 424 ) / 35616

= 672 / 424

= 672

Step2:

LCM(8, 455) = 3640

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

= 8 / 455

= 8

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 672, 424, 455, 162 is 1
