The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 531 are 3 x 3 x 59

Prime factors of 705 are 3 x 5 x 47

Prime factors of 287 are 7 x 41

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

Given numbers are 145, 531, 705, 287

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

Apply this formula for all numbers.

Step1:

LCM(145, 531) = 76995

GCD(145, 531) = ( 145 x 531 ) / 76995

= 145 / 531

= 145

Step2:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 145, 531, 705, 287 is 1
