Given numbers are 720, 494, 787, 538

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 494 are 2 x 13 x 19

Prime factors of 787 are 787

Prime factors of 538 are 2 x 269

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

Given numbers are 720, 494, 787, 538

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

Apply this formula for all numbers.

Step1:

LCM(720, 494) = 177840

GCD(720, 494) = ( 720 x 494 ) / 177840

= 720 / 494

= 720

Step2:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 720, 494, 787, 538 is 1
