Given numbers are 454, 155, 217, 556

The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 155 are 5 x 31

Prime factors of 217 are 7 x 31

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 454, 155, 217, 556

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

Apply this formula for all numbers.

Step1:

LCM(454, 155) = 70370

GCD(454, 155) = ( 454 x 155 ) / 70370

= 454 / 155

= 454

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 454, 155, 217, 556 is 1
