Given numbers are 246, 390, 391, 469

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

Apply this formula for all numbers.

Step1:

LCM(246, 390) = 15990

GCD(246, 390) = ( 246 x 390 ) / 15990

= 246 / 390

= 246

Step2:

LCM(6, 391) = 2346

GCD(6, 391) = ( 6 x 391 ) / 2346

= 6 / 391

= 6

Step3:

LCM(1, 469) = 469

GCD(1, 469) = ( 1 x 469 ) / 469

= 1 / 469

= 1

So, Greatest Common Divisor of 246, 390, 391, 469 is 1
