Given numbers are 408, 290, 788, 839

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

Apply this formula for all numbers.

Step1:

LCM(408, 290) = 59160

GCD(408, 290) = ( 408 x 290 ) / 59160

= 408 / 290

= 408

Step2:

LCM(2, 788) = 788

GCD(2, 788) = ( 2 x 788 ) / 788

= 2 / 788

= 2

Step3:

LCM(2, 839) = 1678

GCD(2, 839) = ( 2 x 839 ) / 1678

= 2 / 839

= 2

So, Greatest Common Divisor of 408, 290, 788, 839 is 1
