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

Apply this formula for all numbers.

Step1:

LCM(801, 999) = 88911

GCD(801, 999) = ( 801 x 999 ) / 88911

= 801 / 999

= 801

Step2:

LCM(9, 643) = 5787

GCD(9, 643) = ( 9 x 643 ) / 5787

= 9 / 643

= 9

So, Greatest Common Divisor of 801, 999, 643 is 1
