The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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 445, 144, 780, 998

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

Apply this formula for all numbers.

Step1:

LCM(445, 144) = 64080

GCD(445, 144) = ( 445 x 144 ) / 64080

= 445 / 144

= 445

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 998) = 998

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

= 1 / 998

= 1

So, Greatest Common Divisor of 445, 144, 780, 998 is 1
