The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 553 are 7 x 79

Prime factors of 454 are 2 x 227

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 945, 553, 454, 221

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

Apply this formula for all numbers.

Step1:

LCM(945, 553) = 74655

GCD(945, 553) = ( 945 x 553 ) / 74655

= 945 / 553

= 945

Step2:

LCM(7, 454) = 3178

GCD(7, 454) = ( 7 x 454 ) / 3178

= 7 / 454

= 7

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 945, 553, 454, 221 is 1
