Given numbers are 357, 420, 331, 443

The list of prime factors of all numbers are

Prime factors of 357 are 3 x 7 x 17

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 331 are 331

Prime factors of 443 are 443

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

Given numbers are 357, 420, 331, 443

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

Apply this formula for all numbers.

Step1:

LCM(357, 420) = 7140

GCD(357, 420) = ( 357 x 420 ) / 7140

= 357 / 420

= 357

Step2:

LCM(21, 331) = 6951

GCD(21, 331) = ( 21 x 331 ) / 6951

= 21 / 331

= 21

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 357, 420, 331, 443 is 1
