Given numbers are 805, 187, 721

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

Apply this formula for all numbers.

Step1:

LCM(805, 187) = 150535

GCD(805, 187) = ( 805 x 187 ) / 150535

= 805 / 187

= 805

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 805, 187, 721 is 1
