Given numbers are 455, 845, 261

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

Apply this formula for all numbers.

Step1:

LCM(455, 845) = 5915

GCD(455, 845) = ( 455 x 845 ) / 5915

= 455 / 845

= 455

Step2:

LCM(65, 261) = 16965

GCD(65, 261) = ( 65 x 261 ) / 16965

= 65 / 261

= 65

So, Greatest Common Divisor of 455, 845, 261 is 1
