Given numbers are 813, 701, 644, 671

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 701 are 701

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

Prime factors of 671 are 11 x 61

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

Given numbers are 813, 701, 644, 671

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

Apply this formula for all numbers.

Step1:

LCM(813, 701) = 569913

GCD(813, 701) = ( 813 x 701 ) / 569913

= 813 / 701

= 813

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 813, 701, 644, 671 is 1
