Given numbers are 343, 557, 990, 568

The list of prime factors of all numbers are

Prime factors of 343 are 7 x 7 x 7

Prime factors of 557 are 557

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 568 are 2 x 2 x 2 x 71

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

Given numbers are 343, 557, 990, 568

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

Apply this formula for all numbers.

Step1:

LCM(343, 557) = 191051

GCD(343, 557) = ( 343 x 557 ) / 191051

= 343 / 557

= 343

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

So, Greatest Common Divisor of 343, 557, 990, 568 is 1
