Given numbers are 205, 858, 985, 702

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 985 are 5 x 197

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 205, 858, 985, 702

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

Apply this formula for all numbers.

Step1:

LCM(205, 858) = 175890

GCD(205, 858) = ( 205 x 858 ) / 175890

= 205 / 858

= 205

Step2:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 205, 858, 985, 702 is 1
