Given numbers are 819, 645, 917, 178

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

Apply this formula for all numbers.

Step1:

LCM(819, 645) = 176085

GCD(819, 645) = ( 819 x 645 ) / 176085

= 819 / 645

= 819

Step2:

LCM(3, 917) = 2751

GCD(3, 917) = ( 3 x 917 ) / 2751

= 3 / 917

= 3

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 819, 645, 917, 178 is 1
