Given numbers are 645, 674, 511, 548

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 674 are 2 x 337

Prime factors of 511 are 7 x 73

Prime factors of 548 are 2 x 2 x 137

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

Given numbers are 645, 674, 511, 548

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

Apply this formula for all numbers.

Step1:

LCM(645, 674) = 434730

GCD(645, 674) = ( 645 x 674 ) / 434730

= 645 / 674

= 645

Step2:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

Step3:

LCM(1, 548) = 548

GCD(1, 548) = ( 1 x 548 ) / 548

= 1 / 548

= 1

So, Greatest Common Divisor of 645, 674, 511, 548 is 1
