Given numbers are 170, 261, 409, 869

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 261 are 3 x 3 x 29

Prime factors of 409 are 409

Prime factors of 869 are 11 x 79

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

Given numbers are 170, 261, 409, 869

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

Apply this formula for all numbers.

Step1:

LCM(170, 261) = 44370

GCD(170, 261) = ( 170 x 261 ) / 44370

= 170 / 261

= 170

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 170, 261, 409, 869 is 1
