Given numbers are 865, 220, 40

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

Apply this formula for all numbers.

Step1:

LCM(865, 220) = 38060

GCD(865, 220) = ( 865 x 220 ) / 38060

= 865 / 220

= 865

Step2:

LCM(5, 40) = 40

GCD(5, 40) = ( 5 x 40 ) / 40

= 5 / 40

= 5

So, Greatest Common Divisor of 865, 220, 40 is 5
