Given numbers are 813, 755, 540, 649

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 755 are 5 x 151

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

Prime factors of 649 are 11 x 59

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

Given numbers are 813, 755, 540, 649

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

Apply this formula for all numbers.

Step1:

LCM(813, 755) = 613815

GCD(813, 755) = ( 813 x 755 ) / 613815

= 813 / 755

= 813

Step2:

LCM(1, 540) = 540

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

= 1 / 540

= 1

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 813, 755, 540, 649 is 1
