Given numbers are 221, 261, 352, 308

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 261 are 3 x 3 x 29

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 221, 261, 352, 308

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

Apply this formula for all numbers.

Step1:

LCM(221, 261) = 57681

GCD(221, 261) = ( 221 x 261 ) / 57681

= 221 / 261

= 221

Step2:

LCM(1, 352) = 352

GCD(1, 352) = ( 1 x 352 ) / 352

= 1 / 352

= 1

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 221, 261, 352, 308 is 1
