Given numbers are 140, 928, 831, 686

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 831 are 3 x 277

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 140, 928, 831, 686

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

Apply this formula for all numbers.

Step1:

LCM(140, 928) = 32480

GCD(140, 928) = ( 140 x 928 ) / 32480

= 140 / 928

= 140

Step2:

LCM(4, 831) = 3324

GCD(4, 831) = ( 4 x 831 ) / 3324

= 4 / 831

= 4

Step3:

LCM(1, 686) = 686

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

= 1 / 686

= 1

So, Greatest Common Divisor of 140, 928, 831, 686 is 1
