Given numbers are 644, 557, 326, 511

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 557 are 557

Prime factors of 326 are 2 x 163

Prime factors of 511 are 7 x 73

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

Given numbers are 644, 557, 326, 511

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

Apply this formula for all numbers.

Step1:

LCM(644, 557) = 358708

GCD(644, 557) = ( 644 x 557 ) / 358708

= 644 / 557

= 644

Step2:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

Step3:

LCM(1, 511) = 511

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

= 1 / 511

= 1

So, Greatest Common Divisor of 644, 557, 326, 511 is 1
