Given numbers are 249, 290, 243, 542

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

Apply this formula for all numbers.

Step1:

LCM(249, 290) = 72210

GCD(249, 290) = ( 249 x 290 ) / 72210

= 249 / 290

= 249

Step2:

LCM(1, 243) = 243

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

= 1 / 243

= 1

Step3:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

So, Greatest Common Divisor of 249, 290, 243, 542 is 1
