Given numbers are 805, 437, 623, 305

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

Apply this formula for all numbers.

Step1:

LCM(805, 437) = 15295

GCD(805, 437) = ( 805 x 437 ) / 15295

= 805 / 437

= 805

Step2:

LCM(23, 623) = 14329

GCD(23, 623) = ( 23 x 623 ) / 14329

= 23 / 623

= 23

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 805, 437, 623, 305 is 1
