Given numbers are 349, 528, 687, 221

The list of prime factors of all numbers are

Prime factors of 349 are 349

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 687 are 3 x 229

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 349, 528, 687, 221

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

Apply this formula for all numbers.

Step1:

LCM(349, 528) = 184272

GCD(349, 528) = ( 349 x 528 ) / 184272

= 349 / 528

= 349

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 349, 528, 687, 221 is 1
