Given numbers are 648, 804, 755, 813

The list of prime factors of all numbers are

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

Prime factors of 804 are 2 x 2 x 3 x 67

Prime factors of 755 are 5 x 151

Prime factors of 813 are 3 x 271

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

Given numbers are 648, 804, 755, 813

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

Apply this formula for all numbers.

Step1:

LCM(648, 804) = 43416

GCD(648, 804) = ( 648 x 804 ) / 43416

= 648 / 804

= 648

Step2:

LCM(12, 755) = 9060

GCD(12, 755) = ( 12 x 755 ) / 9060

= 12 / 755

= 12

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 648, 804, 755, 813 is 1
