Given numbers are 188, 840, 398, 431

The list of prime factors of all numbers are

Prime factors of 188 are 2 x 2 x 47

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 398 are 2 x 199

Prime factors of 431 are 431

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

Given numbers are 188, 840, 398, 431

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

Apply this formula for all numbers.

Step1:

LCM(188, 840) = 39480

GCD(188, 840) = ( 188 x 840 ) / 39480

= 188 / 840

= 188

Step2:

LCM(4, 398) = 796

GCD(4, 398) = ( 4 x 398 ) / 796

= 4 / 398

= 4

Step3:

LCM(2, 431) = 862

GCD(2, 431) = ( 2 x 431 ) / 862

= 2 / 431

= 2

So, Greatest Common Divisor of 188, 840, 398, 431 is 1
