Given numbers are 391, 563, 170, 183

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

Apply this formula for all numbers.

Step1:

LCM(391, 563) = 220133

GCD(391, 563) = ( 391 x 563 ) / 220133

= 391 / 563

= 391

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 183) = 183

GCD(1, 183) = ( 1 x 183 ) / 183

= 1 / 183

= 1

So, Greatest Common Divisor of 391, 563, 170, 183 is 1
