Given numbers are 819, 143, 161, 617

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

Apply this formula for all numbers.

Step1:

LCM(819, 143) = 9009

GCD(819, 143) = ( 819 x 143 ) / 9009

= 819 / 143

= 819

Step2:

LCM(13, 161) = 2093

GCD(13, 161) = ( 13 x 161 ) / 2093

= 13 / 161

= 13

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 819, 143, 161, 617 is 1
