Given numbers are 815, 309, 457, 632

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

Apply this formula for all numbers.

Step1:

LCM(815, 309) = 251835

GCD(815, 309) = ( 815 x 309 ) / 251835

= 815 / 309

= 815

Step2:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

Step3:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

So, Greatest Common Divisor of 815, 309, 457, 632 is 1
