Given numbers are 105, 749, 405, 558

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 749 are 7 x 107

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 105, 749, 405, 558

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

Apply this formula for all numbers.

Step1:

LCM(105, 749) = 11235

GCD(105, 749) = ( 105 x 749 ) / 11235

= 105 / 749

= 105

Step2:

LCM(7, 405) = 2835

GCD(7, 405) = ( 7 x 405 ) / 2835

= 7 / 405

= 7

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 105, 749, 405, 558 is 1
