Given numbers are 209, 838, 450, 203

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

Apply this formula for all numbers.

Step1:

LCM(209, 838) = 175142

GCD(209, 838) = ( 209 x 838 ) / 175142

= 209 / 838

= 209

Step2:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

Step3:

LCM(1, 203) = 203

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

= 1 / 203

= 1

So, Greatest Common Divisor of 209, 838, 450, 203 is 1
