Given numbers are 820, 178, 499, 831

The list of prime factors of all numbers are

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

Prime factors of 178 are 2 x 89

Prime factors of 499 are 499

Prime factors of 831 are 3 x 277

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

Given numbers are 820, 178, 499, 831

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

Apply this formula for all numbers.

Step1:

LCM(820, 178) = 72980

GCD(820, 178) = ( 820 x 178 ) / 72980

= 820 / 178

= 820

Step2:

LCM(2, 499) = 998

GCD(2, 499) = ( 2 x 499 ) / 998

= 2 / 499

= 2

Step3:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 820, 178, 499, 831 is 1
