Given numbers are 831, 287, 100, 785

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 287 are 7 x 41

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 785 are 5 x 157

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

Given numbers are 831, 287, 100, 785

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

Apply this formula for all numbers.

Step1:

LCM(831, 287) = 238497

GCD(831, 287) = ( 831 x 287 ) / 238497

= 831 / 287

= 831

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 831, 287, 100, 785 is 1
