Given numbers are 391, 687, 174, 710

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

Apply this formula for all numbers.

Step1:

LCM(391, 687) = 268617

GCD(391, 687) = ( 391 x 687 ) / 268617

= 391 / 687

= 391

Step2:

LCM(1, 174) = 174

GCD(1, 174) = ( 1 x 174 ) / 174

= 1 / 174

= 1

Step3:

LCM(1, 710) = 710

GCD(1, 710) = ( 1 x 710 ) / 710

= 1 / 710

= 1

So, Greatest Common Divisor of 391, 687, 174, 710 is 1
