Given numbers are 915, 165, 605, 231

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

Apply this formula for all numbers.

Step1:

LCM(915, 165) = 10065

GCD(915, 165) = ( 915 x 165 ) / 10065

= 915 / 165

= 915

Step2:

LCM(15, 605) = 1815

GCD(15, 605) = ( 15 x 605 ) / 1815

= 15 / 605

= 15

Step3:

LCM(5, 231) = 1155

GCD(5, 231) = ( 5 x 231 ) / 1155

= 5 / 231

= 5

So, Greatest Common Divisor of 915, 165, 605, 231 is 1
