Given numbers are 831, 143, 375, 686

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 143 are 11 x 13

Prime factors of 375 are 3 x 5 x 5 x 5

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 831, 143, 375, 686

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

Apply this formula for all numbers.

Step1:

LCM(831, 143) = 118833

GCD(831, 143) = ( 831 x 143 ) / 118833

= 831 / 143

= 831

Step2:

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

= 1 / 375

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 831, 143, 375, 686 is 1
