Given numbers are 391, 724, 859, 491

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

Apply this formula for all numbers.

Step1:

LCM(391, 724) = 283084

GCD(391, 724) = ( 391 x 724 ) / 283084

= 391 / 724

= 391

Step2:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 391, 724, 859, 491 is 1
