Given numbers are 290, 836, 144, 403

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 403 are 13 x 31

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

Given numbers are 290, 836, 144, 403

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

Apply this formula for all numbers.

Step1:

LCM(290, 836) = 121220

GCD(290, 836) = ( 290 x 836 ) / 121220

= 290 / 836

= 290

Step2:

LCM(2, 144) = 144

GCD(2, 144) = ( 2 x 144 ) / 144

= 2 / 144

= 2

Step3:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

So, Greatest Common Divisor of 290, 836, 144, 403 is 1
