Given numbers are 238, 651, 828, 423

The list of prime factors of all numbers are

Prime factors of 238 are 2 x 7 x 17

Prime factors of 651 are 3 x 7 x 31

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 238, 651, 828, 423

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

Apply this formula for all numbers.

Step1:

LCM(238, 651) = 22134

GCD(238, 651) = ( 238 x 651 ) / 22134

= 238 / 651

= 238

Step2:

LCM(7, 828) = 5796

GCD(7, 828) = ( 7 x 828 ) / 5796

= 7 / 828

= 7

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 238, 651, 828, 423 is 1
