Given numbers are 290, 638, 205

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

Apply this formula for all numbers.

Step1:

LCM(290, 638) = 3190

GCD(290, 638) = ( 290 x 638 ) / 3190

= 290 / 638

= 290

Step2:

LCM(58, 205) = 11890

GCD(58, 205) = ( 58 x 205 ) / 11890

= 58 / 205

= 58

So, Greatest Common Divisor of 290, 638, 205 is 1
