Given numbers are 825, 393, 489, 278

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

Apply this formula for all numbers.

Step1:

LCM(825, 393) = 108075

GCD(825, 393) = ( 825 x 393 ) / 108075

= 825 / 393

= 825

Step2:

LCM(3, 489) = 489

GCD(3, 489) = ( 3 x 489 ) / 489

= 3 / 489

= 3

Step3:

LCM(3, 278) = 834

GCD(3, 278) = ( 3 x 278 ) / 834

= 3 / 278

= 3

So, Greatest Common Divisor of 825, 393, 489, 278 is 1
