The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 790 are 2 x 5 x 79

Prime factors of 274 are 2 x 137

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 454, 790, 274, 561

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

Apply this formula for all numbers.

Step1:

LCM(454, 790) = 179330

GCD(454, 790) = ( 454 x 790 ) / 179330

= 454 / 790

= 454

Step2:

LCM(2, 274) = 274

GCD(2, 274) = ( 2 x 274 ) / 274

= 2 / 274

= 2

Step3:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

So, Greatest Common Divisor of 454, 790, 274, 561 is 1
