Given numbers are 477, 261, 512, 815

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

Apply this formula for all numbers.

Step1:

LCM(477, 261) = 13833

GCD(477, 261) = ( 477 x 261 ) / 13833

= 477 / 261

= 477

Step2:

LCM(9, 512) = 4608

GCD(9, 512) = ( 9 x 512 ) / 4608

= 9 / 512

= 9

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 477, 261, 512, 815 is 1
