Given numbers are 206, 438, 822, 203

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

Apply this formula for all numbers.

Step1:

LCM(206, 438) = 45114

GCD(206, 438) = ( 206 x 438 ) / 45114

= 206 / 438

= 206

Step2:

LCM(2, 822) = 822

GCD(2, 822) = ( 2 x 822 ) / 822

= 2 / 822

= 2

Step3:

LCM(2, 203) = 406

GCD(2, 203) = ( 2 x 203 ) / 406

= 2 / 203

= 2

So, Greatest Common Divisor of 206, 438, 822, 203 is 1
