Given numbers are 455, 909, 221, 773

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

Apply this formula for all numbers.

Step1:

LCM(455, 909) = 413595

GCD(455, 909) = ( 455 x 909 ) / 413595

= 455 / 909

= 455

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

So, Greatest Common Divisor of 455, 909, 221, 773 is 1
