Given numbers are 390, 438, 467, 203

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

Apply this formula for all numbers.

Step1:

LCM(390, 438) = 28470

GCD(390, 438) = ( 390 x 438 ) / 28470

= 390 / 438

= 390

Step2:

LCM(6, 467) = 2802

GCD(6, 467) = ( 6 x 467 ) / 2802

= 6 / 467

= 6

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 390, 438, 467, 203 is 1
