Given numbers are 336, 455, 458, 221

The list of prime factors of all numbers are

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 455 are 5 x 7 x 13

Prime factors of 458 are 2 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 336, 455, 458, 221

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

Apply this formula for all numbers.

Step1:

LCM(336, 455) = 21840

GCD(336, 455) = ( 336 x 455 ) / 21840

= 336 / 455

= 336

Step2:

LCM(7, 458) = 3206

GCD(7, 458) = ( 7 x 458 ) / 3206

= 7 / 458

= 7

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 336, 455, 458, 221 is 1
