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

Apply this formula for all numbers.

Step1:

LCM(455, 861) = 55965

GCD(455, 861) = ( 455 x 861 ) / 55965

= 455 / 861

= 455

Step2:

LCM(7, 469) = 469

GCD(7, 469) = ( 7 x 469 ) / 469

= 7 / 469

= 7

So, Greatest Common Divisor of 455, 861, 469 is 7
