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

Apply this formula for all numbers.

Step1:

LCM(249, 636) = 52788

GCD(249, 636) = ( 249 x 636 ) / 52788

= 249 / 636

= 249

Step2:

LCM(3, 219) = 219

GCD(3, 219) = ( 3 x 219 ) / 219

= 3 / 219

= 3

Step3:

LCM(3, 891) = 891

GCD(3, 891) = ( 3 x 891 ) / 891

= 3 / 891

= 3

So, Greatest Common Divisor of 249, 636, 219, 891 is 3
