Given numbers are 511, 307, 840, 648

The list of prime factors of all numbers are

Prime factors of 511 are 7 x 73

Prime factors of 307 are 307

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 511, 307, 840, 648

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

Apply this formula for all numbers.

Step1:

LCM(511, 307) = 156877

GCD(511, 307) = ( 511 x 307 ) / 156877

= 511 / 307

= 511

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 511, 307, 840, 648 is 1
