Given numbers are 717, 490, 311, 243

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

Apply this formula for all numbers.

Step1:

LCM(717, 490) = 351330

GCD(717, 490) = ( 717 x 490 ) / 351330

= 717 / 490

= 717

Step2:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 717, 490, 311, 243 is 1
