Given numbers are 249, 464, 561, 543

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

Apply this formula for all numbers.

Step1:

LCM(249, 464) = 115536

GCD(249, 464) = ( 249 x 464 ) / 115536

= 249 / 464

= 249

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

So, Greatest Common Divisor of 249, 464, 561, 543 is 1
