Given numbers are 357, 476, 178, 221

The list of prime factors of all numbers are

Prime factors of 357 are 3 x 7 x 17

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 178 are 2 x 89

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 357, 476, 178, 221

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

Apply this formula for all numbers.

Step1:

LCM(357, 476) = 1428

GCD(357, 476) = ( 357 x 476 ) / 1428

= 357 / 476

= 357

Step2:

LCM(119, 178) = 21182

GCD(119, 178) = ( 119 x 178 ) / 21182

= 119 / 178

= 119

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 357, 476, 178, 221 is 1
