Given numbers are 485, 164, 565, 221

The list of prime factors of all numbers are

Prime factors of 485 are 5 x 97

Prime factors of 164 are 2 x 2 x 41

Prime factors of 565 are 5 x 113

Prime factors of 221 are 13 x 17

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

Given numbers are 485, 164, 565, 221

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

Apply this formula for all numbers.

Step1:

LCM(485, 164) = 79540

GCD(485, 164) = ( 485 x 164 ) / 79540

= 485 / 164

= 485

Step2:

LCM(1, 565) = 565

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

= 1 / 565

= 1

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 485, 164, 565, 221 is 1
