Given numbers are 494, 243, 19, 403

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

Apply this formula for all numbers.

Step1:

LCM(494, 243) = 120042

GCD(494, 243) = ( 494 x 243 ) / 120042

= 494 / 243

= 494

Step2:

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

= 1 / 19

= 1

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 494, 243, 19, 403 is 1
