Given numbers are 445, 817, 552, 221

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 817 are 19 x 43

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

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 445, 817, 552, 221

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

Apply this formula for all numbers.

Step1:

LCM(445, 817) = 363565

GCD(445, 817) = ( 445 x 817 ) / 363565

= 445 / 817

= 445

Step2:

LCM(1, 552) = 552

GCD(1, 552) = ( 1 x 552 ) / 552

= 1 / 552

= 1

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 445, 817, 552, 221 is 1
