Given numbers are 186, 972, 195, 398

The list of prime factors of all numbers are

Prime factors of 186 are 2 x 3 x 31

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 195 are 3 x 5 x 13

Prime factors of 398 are 2 x 199

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

Given numbers are 186, 972, 195, 398

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

Apply this formula for all numbers.

Step1:

LCM(186, 972) = 30132

GCD(186, 972) = ( 186 x 972 ) / 30132

= 186 / 972

= 186

Step2:

LCM(6, 195) = 390

GCD(6, 195) = ( 6 x 195 ) / 390

= 6 / 195

= 6

Step3:

LCM(3, 398) = 1194

GCD(3, 398) = ( 3 x 398 ) / 1194

= 3 / 398

= 3

So, Greatest Common Divisor of 186, 972, 195, 398 is 1
