Given numbers are 249, 591, 562, 861

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

Apply this formula for all numbers.

Step1:

LCM(249, 591) = 49053

GCD(249, 591) = ( 249 x 591 ) / 49053

= 249 / 591

= 249

Step2:

LCM(3, 562) = 1686

GCD(3, 562) = ( 3 x 562 ) / 1686

= 3 / 562

= 3

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 249, 591, 562, 861 is 1
