Given numbers are 810, 159, 690, 298

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 159 are 3 x 53

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

Prime factors of 298 are 2 x 149

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

Given numbers are 810, 159, 690, 298

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

Apply this formula for all numbers.

Step1:

LCM(810, 159) = 42930

GCD(810, 159) = ( 810 x 159 ) / 42930

= 810 / 159

= 810

Step2:

LCM(3, 690) = 690

GCD(3, 690) = ( 3 x 690 ) / 690

= 3 / 690

= 3

Step3:

LCM(3, 298) = 894

GCD(3, 298) = ( 3 x 298 ) / 894

= 3 / 298

= 3

So, Greatest Common Divisor of 810, 159, 690, 298 is 1
