Given numbers are 393, 690, 50, 178

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

Apply this formula for all numbers.

Step1:

LCM(393, 690) = 90390

GCD(393, 690) = ( 393 x 690 ) / 90390

= 393 / 690

= 393

Step2:

LCM(3, 50) = 150

GCD(3, 50) = ( 3 x 50 ) / 150

= 3 / 50

= 3

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 393, 690, 50, 178 is 1
