Given numbers are 655, 259, 121, 806

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

Apply this formula for all numbers.

Step1:

LCM(655, 259) = 169645

GCD(655, 259) = ( 655 x 259 ) / 169645

= 655 / 259

= 655

Step2:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

Step3:

LCM(1, 806) = 806

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

= 1 / 806

= 1

So, Greatest Common Divisor of 655, 259, 121, 806 is 1
