Given numbers are 265, 470, 405

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

Apply this formula for all numbers.

Step1:

LCM(265, 470) = 24910

GCD(265, 470) = ( 265 x 470 ) / 24910

= 265 / 470

= 265

Step2:

LCM(5, 405) = 405

GCD(5, 405) = ( 5 x 405 ) / 405

= 5 / 405

= 5

So, Greatest Common Divisor of 265, 470, 405 is 5
