Given numbers are 219, 249, 788, 320

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

Apply this formula for all numbers.

Step1:

LCM(219, 249) = 18177

GCD(219, 249) = ( 219 x 249 ) / 18177

= 219 / 249

= 219

Step2:

LCM(3, 788) = 2364

GCD(3, 788) = ( 3 x 788 ) / 2364

= 3 / 788

= 3

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 219, 249, 788, 320 is 1
