Given numbers are 915, 819, 649, 413

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

Apply this formula for all numbers.

Step1:

LCM(915, 819) = 249795

GCD(915, 819) = ( 915 x 819 ) / 249795

= 915 / 819

= 915

Step2:

LCM(3, 649) = 1947

GCD(3, 649) = ( 3 x 649 ) / 1947

= 3 / 649

= 3

Step3:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

So, Greatest Common Divisor of 915, 819, 649, 413 is 1
