Given numbers are 305, 469, 161, 860

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 469 are 7 x 67

Prime factors of 161 are 7 x 23

Prime factors of 860 are 2 x 2 x 5 x 43

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

Given numbers are 305, 469, 161, 860

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

Apply this formula for all numbers.

Step1:

LCM(305, 469) = 143045

GCD(305, 469) = ( 305 x 469 ) / 143045

= 305 / 469

= 305

Step2:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 305, 469, 161, 860 is 1
