Given numbers are 623, 399, 563, 417

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

Apply this formula for all numbers.

Step1:

LCM(623, 399) = 35511

GCD(623, 399) = ( 623 x 399 ) / 35511

= 623 / 399

= 623

Step2:

LCM(7, 563) = 3941

GCD(7, 563) = ( 7 x 563 ) / 3941

= 7 / 563

= 7

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 623, 399, 563, 417 is 1
