Given numbers are 398, 687, 726

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

Apply this formula for all numbers.

Step1:

LCM(398, 687) = 273426

GCD(398, 687) = ( 398 x 687 ) / 273426

= 398 / 687

= 398

Step2:

LCM(1, 726) = 726

GCD(1, 726) = ( 1 x 726 ) / 726

= 1 / 726

= 1

So, Greatest Common Divisor of 398, 687, 726 is 1
