Given numbers are 738, 720, 643, 998

The list of prime factors of all numbers are

Prime factors of 738 are 2 x 3 x 3 x 41

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

Prime factors of 643 are 643

Prime factors of 998 are 2 x 499

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

Given numbers are 738, 720, 643, 998

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

Apply this formula for all numbers.

Step1:

LCM(738, 720) = 29520

GCD(738, 720) = ( 738 x 720 ) / 29520

= 738 / 720

= 738

Step2:

LCM(18, 643) = 11574

GCD(18, 643) = ( 18 x 643 ) / 11574

= 18 / 643

= 18

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 738, 720, 643, 998 is 1
