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

Apply this formula for all numbers.

Step1:

LCM(821, 208) = 170768

GCD(821, 208) = ( 821 x 208 ) / 170768

= 821 / 208

= 821

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

So, Greatest Common Divisor of 821, 208, 475 is 1
