Given numbers are 831, 920, 515, 349

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 515 are 5 x 103

Prime factors of 349 are 349

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

Given numbers are 831, 920, 515, 349

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

Apply this formula for all numbers.

Step1:

LCM(831, 920) = 764520

GCD(831, 920) = ( 831 x 920 ) / 764520

= 831 / 920

= 831

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 831, 920, 515, 349 is 1
