Given numbers are 489, 297, 136, 790

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

Apply this formula for all numbers.

Step1:

LCM(489, 297) = 48411

GCD(489, 297) = ( 489 x 297 ) / 48411

= 489 / 297

= 489

Step2:

LCM(3, 136) = 408

GCD(3, 136) = ( 3 x 136 ) / 408

= 3 / 136

= 3

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 489, 297, 136, 790 is 1
