Given numbers are 290, 408, 305, 606

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 305 are 5 x 61

Prime factors of 606 are 2 x 3 x 101

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

Given numbers are 290, 408, 305, 606

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

Apply this formula for all numbers.

Step1:

LCM(290, 408) = 59160

GCD(290, 408) = ( 290 x 408 ) / 59160

= 290 / 408

= 290

Step2:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

Step3:

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

= 1 / 606

= 1

So, Greatest Common Divisor of 290, 408, 305, 606 is 1
