Given numbers are 290, 689, 408, 102

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 689 are 13 x 53

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

Prime factors of 102 are 2 x 3 x 17

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

Given numbers are 290, 689, 408, 102

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

Apply this formula for all numbers.

Step1:

LCM(290, 689) = 199810

GCD(290, 689) = ( 290 x 689 ) / 199810

= 290 / 689

= 290

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 290, 689, 408, 102 is 1
