The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 647, 819, 540, 172

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

Apply this formula for all numbers.

Step1:

LCM(647, 819) = 529893

GCD(647, 819) = ( 647 x 819 ) / 529893

= 647 / 819

= 647

Step2:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 647, 819, 540, 172 is 1
