Given numbers are 258, 170, 840, 995

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 170 are 2 x 5 x 17

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 995 are 5 x 199

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

Given numbers are 258, 170, 840, 995

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

Apply this formula for all numbers.

Step1:

LCM(258, 170) = 21930

GCD(258, 170) = ( 258 x 170 ) / 21930

= 258 / 170

= 258

Step2:

LCM(2, 840) = 840

GCD(2, 840) = ( 2 x 840 ) / 840

= 2 / 840

= 2

Step3:

LCM(2, 995) = 1990

GCD(2, 995) = ( 2 x 995 ) / 1990

= 2 / 995

= 2

So, Greatest Common Divisor of 258, 170, 840, 995 is 1
