Given numbers are 408, 290, 111, 785

The list of prime factors of all numbers are

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

Prime factors of 290 are 2 x 5 x 29

Prime factors of 111 are 3 x 37

Prime factors of 785 are 5 x 157

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

Given numbers are 408, 290, 111, 785

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

Apply this formula for all numbers.

Step1:

LCM(408, 290) = 59160

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

= 408 / 290

= 408

Step2:

LCM(2, 111) = 222

GCD(2, 111) = ( 2 x 111 ) / 222

= 2 / 111

= 2

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 408, 290, 111, 785 is 1
