Given numbers are 805, 139, 12, 234

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

Apply this formula for all numbers.

Step1:

LCM(805, 139) = 111895

GCD(805, 139) = ( 805 x 139 ) / 111895

= 805 / 139

= 805

Step2:

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

= 1 / 12

= 1

Step3:

LCM(1, 234) = 234

GCD(1, 234) = ( 1 x 234 ) / 234

= 1 / 234

= 1

So, Greatest Common Divisor of 805, 139, 12, 234 is 1
