The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 222 are 2 x 3 x 37

Prime factors of 815 are 5 x 163

Prime factors of 178 are 2 x 89

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

Given numbers are 454, 222, 815, 178

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

Apply this formula for all numbers.

Step1:

LCM(454, 222) = 50394

GCD(454, 222) = ( 454 x 222 ) / 50394

= 454 / 222

= 454

Step2:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 454, 222, 815, 178 is 1
