Given numbers are 654, 815, 231

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

Apply this formula for all numbers.

Step1:

LCM(654, 815) = 533010

GCD(654, 815) = ( 654 x 815 ) / 533010

= 654 / 815

= 654

Step2:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 654, 815, 231 is 1
