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

Apply this formula for all numbers.

Step1:

LCM(805, 865) = 139265

GCD(805, 865) = ( 805 x 865 ) / 139265

= 805 / 865

= 805

Step2:

LCM(5, 260) = 260

GCD(5, 260) = ( 5 x 260 ) / 260

= 5 / 260

= 5

Step3:

LCM(5, 545) = 545

GCD(5, 545) = ( 5 x 545 ) / 545

= 5 / 545

= 5

So, Greatest Common Divisor of 805, 865, 260, 545 is 5
