Given numbers are 831, 238, 402, 691

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 238 are 2 x 7 x 17

Prime factors of 402 are 2 x 3 x 67

Prime factors of 691 are 691

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

Given numbers are 831, 238, 402, 691

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

Apply this formula for all numbers.

Step1:

LCM(831, 238) = 197778

GCD(831, 238) = ( 831 x 238 ) / 197778

= 831 / 238

= 831

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 831, 238, 402, 691 is 1
