Given numbers are 646, 923, 393, 699

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

Apply this formula for all numbers.

Step1:

LCM(646, 923) = 596258

GCD(646, 923) = ( 646 x 923 ) / 596258

= 646 / 923

= 646

Step2:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

Step3:

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

= 1 / 699

= 1

So, Greatest Common Divisor of 646, 923, 393, 699 is 1
