Given numbers are 820, 874, 431, 168

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 874 are 2 x 19 x 23

Prime factors of 431 are 431

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 820, 874, 431, 168

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

Apply this formula for all numbers.

Step1:

LCM(820, 874) = 358340

GCD(820, 874) = ( 820 x 874 ) / 358340

= 820 / 874

= 820

Step2:

LCM(2, 431) = 862

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

= 2 / 431

= 2

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 820, 874, 431, 168 is 1
