Given numbers are 305, 192, 620, 442

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 305, 192, 620, 442

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

Apply this formula for all numbers.

Step1:

LCM(305, 192) = 58560

GCD(305, 192) = ( 305 x 192 ) / 58560

= 305 / 192

= 305

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 305, 192, 620, 442 is 1
