Given numbers are 205, 455, 703, 909

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

Apply this formula for all numbers.

Step1:

LCM(205, 455) = 18655

GCD(205, 455) = ( 205 x 455 ) / 18655

= 205 / 455

= 205

Step2:

LCM(5, 703) = 3515

GCD(5, 703) = ( 5 x 703 ) / 3515

= 5 / 703

= 5

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 205, 455, 703, 909 is 1
