Given numbers are 393, 338, 164, 878

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

Apply this formula for all numbers.

Step1:

LCM(393, 338) = 132834

GCD(393, 338) = ( 393 x 338 ) / 132834

= 393 / 338

= 393

Step2:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 393, 338, 164, 878 is 1
