Given numbers are 279, 213, 406, 345

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

Apply this formula for all numbers.

Step1:

LCM(279, 213) = 19809

GCD(279, 213) = ( 279 x 213 ) / 19809

= 279 / 213

= 279

Step2:

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

= 3 / 406

= 3

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 279, 213, 406, 345 is 1
