Given numbers are 357, 819, 181, 243

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

Apply this formula for all numbers.

Step1:

LCM(357, 819) = 13923

GCD(357, 819) = ( 357 x 819 ) / 13923

= 357 / 819

= 357

Step2:

LCM(21, 181) = 3801

GCD(21, 181) = ( 21 x 181 ) / 3801

= 21 / 181

= 21

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 357, 819, 181, 243 is 1
