Given numbers are 290, 415, 861, 684

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 415 are 5 x 83

Prime factors of 861 are 3 x 7 x 41

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 290, 415, 861, 684

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

Apply this formula for all numbers.

Step1:

LCM(290, 415) = 24070

GCD(290, 415) = ( 290 x 415 ) / 24070

= 290 / 415

= 290

Step2:

LCM(5, 861) = 4305

GCD(5, 861) = ( 5 x 861 ) / 4305

= 5 / 861

= 5

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 290, 415, 861, 684 is 1
