Given numbers are 856, 768, 409, 471

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

Apply this formula for all numbers.

Step1:

LCM(856, 768) = 82176

GCD(856, 768) = ( 856 x 768 ) / 82176

= 856 / 768

= 856

Step2:

LCM(8, 409) = 3272

GCD(8, 409) = ( 8 x 409 ) / 3272

= 8 / 409

= 8

Step3:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

So, Greatest Common Divisor of 856, 768, 409, 471 is 1
