Given numbers are 831, 211, 385, 581

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

Apply this formula for all numbers.

Step1:

LCM(831, 211) = 175341

GCD(831, 211) = ( 831 x 211 ) / 175341

= 831 / 211

= 831

Step2:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 831, 211, 385, 581 is 1
