Given numbers are 290, 165, 690, 804

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 165 are 3 x 5 x 11

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

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

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

Given numbers are 290, 165, 690, 804

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

Apply this formula for all numbers.

Step1:

LCM(290, 165) = 9570

GCD(290, 165) = ( 290 x 165 ) / 9570

= 290 / 165

= 290

Step2:

LCM(5, 690) = 690

GCD(5, 690) = ( 5 x 690 ) / 690

= 5 / 690

= 5

Step3:

LCM(5, 804) = 4020

GCD(5, 804) = ( 5 x 804 ) / 4020

= 5 / 804

= 5

So, Greatest Common Divisor of 290, 165, 690, 804 is 1
