Given numbers are 725, 104, 663, 489

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

Apply this formula for all numbers.

Step1:

LCM(725, 104) = 75400

GCD(725, 104) = ( 725 x 104 ) / 75400

= 725 / 104

= 725

Step2:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 725, 104, 663, 489 is 1
