Given numbers are 343, 397, 546, 312

The list of prime factors of all numbers are

Prime factors of 343 are 7 x 7 x 7

Prime factors of 397 are 397

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 343, 397, 546, 312

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

Apply this formula for all numbers.

Step1:

LCM(343, 397) = 136171

GCD(343, 397) = ( 343 x 397 ) / 136171

= 343 / 397

= 343

Step2:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 343, 397, 546, 312 is 1
