Given numbers are 231, 492, 393, 938

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 393 are 3 x 131

Prime factors of 938 are 2 x 7 x 67

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

Given numbers are 231, 492, 393, 938

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

Apply this formula for all numbers.

Step1:

LCM(231, 492) = 37884

GCD(231, 492) = ( 231 x 492 ) / 37884

= 231 / 492

= 231

Step2:

LCM(3, 393) = 393

GCD(3, 393) = ( 3 x 393 ) / 393

= 3 / 393

= 3

Step3:

LCM(3, 938) = 2814

GCD(3, 938) = ( 3 x 938 ) / 2814

= 3 / 938

= 3

So, Greatest Common Divisor of 231, 492, 393, 938 is 1
