Given numbers are 455, 661, 222, 274

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 661 are 661

Prime factors of 222 are 2 x 3 x 37

Prime factors of 274 are 2 x 137

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

Given numbers are 455, 661, 222, 274

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

Apply this formula for all numbers.

Step1:

LCM(455, 661) = 300755

GCD(455, 661) = ( 455 x 661 ) / 300755

= 455 / 661

= 455

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 274) = 274

GCD(1, 274) = ( 1 x 274 ) / 274

= 1 / 274

= 1

So, Greatest Common Divisor of 455, 661, 222, 274 is 1
