Given numbers are 610, 305, 391, 168

The list of prime factors of all numbers are

Prime factors of 610 are 2 x 5 x 61

Prime factors of 305 are 5 x 61

Prime factors of 391 are 17 x 23

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 610, 305, 391, 168

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

Apply this formula for all numbers.

Step1:

LCM(610, 305) = 610

GCD(610, 305) = ( 610 x 305 ) / 610

= 610 / 305

= 610

Step2:

LCM(305, 391) = 119255

GCD(305, 391) = ( 305 x 391 ) / 119255

= 305 / 391

= 305

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 610, 305, 391, 168 is 1
