Given numbers are 720, 912, 987, 145

The list of prime factors of all numbers are

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

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 987 are 3 x 7 x 47

Prime factors of 145 are 5 x 29

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

Given numbers are 720, 912, 987, 145

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

Apply this formula for all numbers.

Step1:

LCM(720, 912) = 13680

GCD(720, 912) = ( 720 x 912 ) / 13680

= 720 / 912

= 720

Step2:

LCM(48, 987) = 15792

GCD(48, 987) = ( 48 x 987 ) / 15792

= 48 / 987

= 48

Step3:

LCM(3, 145) = 435

GCD(3, 145) = ( 3 x 145 ) / 435

= 3 / 145

= 3

So, Greatest Common Divisor of 720, 912, 987, 145 is 1
