Given numbers are 520, 990, 449, 903

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

Apply this formula for all numbers.

Step1:

LCM(520, 990) = 51480

GCD(520, 990) = ( 520 x 990 ) / 51480

= 520 / 990

= 520

Step2:

LCM(10, 449) = 4490

GCD(10, 449) = ( 10 x 449 ) / 4490

= 10 / 449

= 10

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 520, 990, 449, 903 is 1
