Given numbers are 812, 245, 489, 678

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

Apply this formula for all numbers.

Step1:

LCM(812, 245) = 28420

GCD(812, 245) = ( 812 x 245 ) / 28420

= 812 / 245

= 812

Step2:

LCM(7, 489) = 3423

GCD(7, 489) = ( 7 x 489 ) / 3423

= 7 / 489

= 7

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 812, 245, 489, 678 is 1
