Given numbers are 145, 486, 550, 720

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 550 are 2 x 5 x 5 x 11

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 145, 486, 550, 720

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

Apply this formula for all numbers.

Step1:

LCM(145, 486) = 70470

GCD(145, 486) = ( 145 x 486 ) / 70470

= 145 / 486

= 145

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 145, 486, 550, 720 is 1
