Given numbers are 272, 168, 489, 815

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

Apply this formula for all numbers.

Step1:

LCM(272, 168) = 5712

GCD(272, 168) = ( 272 x 168 ) / 5712

= 272 / 168

= 272

Step2:

LCM(8, 489) = 3912

GCD(8, 489) = ( 8 x 489 ) / 3912

= 8 / 489

= 8

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 272, 168, 489, 815 is 1
