Given numbers are 393, 549, 515, 998

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

Apply this formula for all numbers.

Step1:

LCM(393, 549) = 71919

GCD(393, 549) = ( 393 x 549 ) / 71919

= 393 / 549

= 393

Step2:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 393, 549, 515, 998 is 1
