Given numbers are 815, 391, 693, 293

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

Apply this formula for all numbers.

Step1:

LCM(815, 391) = 318665

GCD(815, 391) = ( 815 x 391 ) / 318665

= 815 / 391

= 815

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 293) = 293

GCD(1, 293) = ( 1 x 293 ) / 293

= 1 / 293

= 1

So, Greatest Common Divisor of 815, 391, 693, 293 is 1
