Given numbers are 655, 139, 810

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

Apply this formula for all numbers.

Step1:

LCM(655, 139) = 91045

GCD(655, 139) = ( 655 x 139 ) / 91045

= 655 / 139

= 655

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 655, 139, 810 is 1
