Given numbers are 437, 280, 765, 309

The list of prime factors of all numbers are

Prime factors of 437 are 19 x 23

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 309 are 3 x 103

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

Given numbers are 437, 280, 765, 309

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

Apply this formula for all numbers.

Step1:

LCM(437, 280) = 122360

GCD(437, 280) = ( 437 x 280 ) / 122360

= 437 / 280

= 437

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 437, 280, 765, 309 is 1
