Given numbers are 280, 309, 372, 535

The list of prime factors of all numbers are

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

Prime factors of 309 are 3 x 103

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 535 are 5 x 107

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

Given numbers are 280, 309, 372, 535

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

Apply this formula for all numbers.

Step1:

LCM(280, 309) = 86520

GCD(280, 309) = ( 280 x 309 ) / 86520

= 280 / 309

= 280

Step2:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

Step3:

LCM(1, 535) = 535

GCD(1, 535) = ( 1 x 535 ) / 535

= 1 / 535

= 1

So, Greatest Common Divisor of 280, 309, 372, 535 is 1
