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

Apply this formula for all numbers.

Step1:

LCM(965, 645) = 124485

GCD(965, 645) = ( 965 x 645 ) / 124485

= 965 / 645

= 965

Step2:

LCM(5, 805) = 805

GCD(5, 805) = ( 5 x 805 ) / 805

= 5 / 805

= 5

So, Greatest Common Divisor of 965, 645, 805 is 5
