Given numbers are 810, 575, 425, 165

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

Apply this formula for all numbers.

Step1:

LCM(810, 575) = 93150

GCD(810, 575) = ( 810 x 575 ) / 93150

= 810 / 575

= 810

Step2:

LCM(5, 425) = 425

GCD(5, 425) = ( 5 x 425 ) / 425

= 5 / 425

= 5

Step3:

LCM(5, 165) = 165

GCD(5, 165) = ( 5 x 165 ) / 165

= 5 / 165

= 5

So, Greatest Common Divisor of 810, 575, 425, 165 is 5
