Given numbers are 209, 351, 905

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

Apply this formula for all numbers.

Step1:

LCM(209, 351) = 73359

GCD(209, 351) = ( 209 x 351 ) / 73359

= 209 / 351

= 209

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 209, 351, 905 is 1
