Given numbers are 170, 647, 806

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

Apply this formula for all numbers.

Step1:

LCM(170, 647) = 109990

GCD(170, 647) = ( 170 x 647 ) / 109990

= 170 / 647

= 170

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

So, Greatest Common Divisor of 170, 647, 806 is 1
