Given numbers are 805, 671, 198, 392

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 671 are 11 x 61

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 805, 671, 198, 392

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

Apply this formula for all numbers.

Step1:

LCM(805, 671) = 540155

GCD(805, 671) = ( 805 x 671 ) / 540155

= 805 / 671

= 805

Step2:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 805, 671, 198, 392 is 1
