Given numbers are 143, 405, 760, 312

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

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

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

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 143, 405, 760, 312

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

Apply this formula for all numbers.

Step1:

LCM(143, 405) = 57915

GCD(143, 405) = ( 143 x 405 ) / 57915

= 143 / 405

= 143

Step2:

LCM(1, 760) = 760

GCD(1, 760) = ( 1 x 760 ) / 760

= 1 / 760

= 1

Step3:

LCM(1, 312) = 312

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

= 1 / 312

= 1

So, Greatest Common Divisor of 143, 405, 760, 312 is 1
