Given numbers are 415, 815, 446, 309

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

Apply this formula for all numbers.

Step1:

LCM(415, 815) = 67645

GCD(415, 815) = ( 415 x 815 ) / 67645

= 415 / 815

= 415

Step2:

LCM(5, 446) = 2230

GCD(5, 446) = ( 5 x 446 ) / 2230

= 5 / 446

= 5

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 415, 815, 446, 309 is 1
