Given numbers are 128, 843, 123

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

Apply this formula for all numbers.

Step1:

LCM(128, 843) = 107904

GCD(128, 843) = ( 128 x 843 ) / 107904

= 128 / 843

= 128

Step2:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 128, 843, 123 is 1
