Given numbers are 721, 344, 669

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

Apply this formula for all numbers.

Step1:

LCM(721, 344) = 248024

GCD(721, 344) = ( 721 x 344 ) / 248024

= 721 / 344

= 721

Step2:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 721, 344, 669 is 1
