Given numbers are 821, 869, 204, 603

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

Apply this formula for all numbers.

Step1:

LCM(821, 869) = 713449

GCD(821, 869) = ( 821 x 869 ) / 713449

= 821 / 869

= 821

Step2:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 821, 869, 204, 603 is 1
