Given numbers are 803, 489, 126, 720

The list of prime factors of all numbers are

Prime factors of 803 are 11 x 73

Prime factors of 489 are 3 x 163

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 803, 489, 126, 720

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

Apply this formula for all numbers.

Step1:

LCM(803, 489) = 392667

GCD(803, 489) = ( 803 x 489 ) / 392667

= 803 / 489

= 803

Step2:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 803, 489, 126, 720 is 1
