Given numbers are 243, 744, 668, 178

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

Apply this formula for all numbers.

Step1:

LCM(243, 744) = 60264

GCD(243, 744) = ( 243 x 744 ) / 60264

= 243 / 744

= 243

Step2:

LCM(3, 668) = 2004

GCD(3, 668) = ( 3 x 668 ) / 2004

= 3 / 668

= 3

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 243, 744, 668, 178 is 1
