Given numbers are 831, 290, 209, 538

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 290 are 2 x 5 x 29

Prime factors of 209 are 11 x 19

Prime factors of 538 are 2 x 269

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

Given numbers are 831, 290, 209, 538

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

Apply this formula for all numbers.

Step1:

LCM(831, 290) = 240990

GCD(831, 290) = ( 831 x 290 ) / 240990

= 831 / 290

= 831

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 831, 290, 209, 538 is 1
