Given numbers are 553, 404, 778, 221

The list of prime factors of all numbers are

Prime factors of 553 are 7 x 79

Prime factors of 404 are 2 x 2 x 101

Prime factors of 778 are 2 x 389

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 553, 404, 778, 221

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

Apply this formula for all numbers.

Step1:

LCM(553, 404) = 223412

GCD(553, 404) = ( 553 x 404 ) / 223412

= 553 / 404

= 553

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 553, 404, 778, 221 is 1
