Given numbers are 986, 755, 405, 406

The list of prime factors of all numbers are

Prime factors of 986 are 2 x 17 x 29

Prime factors of 755 are 5 x 151

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

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 986, 755, 405, 406

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

Apply this formula for all numbers.

Step1:

LCM(986, 755) = 744430

GCD(986, 755) = ( 986 x 755 ) / 744430

= 986 / 755

= 986

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 986, 755, 405, 406 is 1
