Given numbers are 221, 268, 335, 455

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 268 are 2 x 2 x 67

Prime factors of 335 are 5 x 67

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 221, 268, 335, 455

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

Apply this formula for all numbers.

Step1:

LCM(221, 268) = 59228

GCD(221, 268) = ( 221 x 268 ) / 59228

= 221 / 268

= 221

Step2:

LCM(1, 335) = 335

GCD(1, 335) = ( 1 x 335 ) / 335

= 1 / 335

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 221, 268, 335, 455 is 1
