Given numbers are 647, 555, 165

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

Apply this formula for all numbers.

Step1:

LCM(647, 555) = 359085

GCD(647, 555) = ( 647 x 555 ) / 359085

= 647 / 555

= 647

Step2:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 647, 555, 165 is 1
