The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 222 are 2 x 3 x 37

Prime factors of 221 are 13 x 17

Prime factors of 565 are 5 x 113

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

Given numbers are 427, 222, 221, 565

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

Apply this formula for all numbers.

Step1:

LCM(427, 222) = 94794

GCD(427, 222) = ( 427 x 222 ) / 94794

= 427 / 222

= 427

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

So, Greatest Common Divisor of 427, 222, 221, 565 is 1
