Given numbers are 705, 434, 280, 539

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 434 are 2 x 7 x 31

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

Prime factors of 539 are 7 x 7 x 11

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

Given numbers are 705, 434, 280, 539

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

Apply this formula for all numbers.

Step1:

LCM(705, 434) = 305970

GCD(705, 434) = ( 705 x 434 ) / 305970

= 705 / 434

= 705

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

So, Greatest Common Divisor of 705, 434, 280, 539 is 1
