Given numbers are 813, 736, 690, 165

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 736 are 2 x 2 x 2 x 2 x 2 x 23

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 813, 736, 690, 165

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

Apply this formula for all numbers.

Step1:

LCM(813, 736) = 598368

GCD(813, 736) = ( 813 x 736 ) / 598368

= 813 / 736

= 813

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 813, 736, 690, 165 is 1
