Given numbers are 455, 480, 294, 161

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 294 are 2 x 3 x 7 x 7

Prime factors of 161 are 7 x 23

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

Given numbers are 455, 480, 294, 161

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

Apply this formula for all numbers.

Step1:

LCM(455, 480) = 43680

GCD(455, 480) = ( 455 x 480 ) / 43680

= 455 / 480

= 455

Step2:

LCM(5, 294) = 1470

GCD(5, 294) = ( 5 x 294 ) / 1470

= 5 / 294

= 5

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 455, 480, 294, 161 is 1
