Given numbers are 390, 699, 923, 458

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

Apply this formula for all numbers.

Step1:

LCM(390, 699) = 90870

GCD(390, 699) = ( 390 x 699 ) / 90870

= 390 / 699

= 390

Step2:

LCM(3, 923) = 2769

GCD(3, 923) = ( 3 x 923 ) / 2769

= 3 / 923

= 3

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 390, 699, 923, 458 is 1
