Given numbers are 249, 780, 287, 346

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

Apply this formula for all numbers.

Step1:

LCM(249, 780) = 64740

GCD(249, 780) = ( 249 x 780 ) / 64740

= 249 / 780

= 249

Step2:

LCM(3, 287) = 861

GCD(3, 287) = ( 3 x 287 ) / 861

= 3 / 287

= 3

Step3:

LCM(1, 346) = 346

GCD(1, 346) = ( 1 x 346 ) / 346

= 1 / 346

= 1

So, Greatest Common Divisor of 249, 780, 287, 346 is 1
