Given numbers are 391, 308, 831, 573

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

Apply this formula for all numbers.

Step1:

LCM(391, 308) = 120428

GCD(391, 308) = ( 391 x 308 ) / 120428

= 391 / 308

= 391

Step2:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

Step3:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

So, Greatest Common Divisor of 391, 308, 831, 573 is 1
