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

Apply this formula for all numbers.

Step1:

LCM(915, 513) = 156465

GCD(915, 513) = ( 915 x 513 ) / 156465

= 915 / 513

= 915

Step2:

LCM(3, 249) = 249

GCD(3, 249) = ( 3 x 249 ) / 249

= 3 / 249

= 3

Step3:

LCM(3, 681) = 681

GCD(3, 681) = ( 3 x 681 ) / 681

= 3 / 681

= 3

So, Greatest Common Divisor of 915, 513, 249, 681 is 3
