Given numbers are 429, 723, 869, 391

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

Apply this formula for all numbers.

Step1:

LCM(429, 723) = 103389

GCD(429, 723) = ( 429 x 723 ) / 103389

= 429 / 723

= 429

Step2:

LCM(3, 869) = 2607

GCD(3, 869) = ( 3 x 869 ) / 2607

= 3 / 869

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 429, 723, 869, 391 is 1
