Given numbers are 720, 495, 987, 683

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 495 are 3 x 3 x 5 x 11

Prime factors of 987 are 3 x 7 x 47

Prime factors of 683 are 683

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

Given numbers are 720, 495, 987, 683

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

Apply this formula for all numbers.

Step1:

LCM(720, 495) = 7920

GCD(720, 495) = ( 720 x 495 ) / 7920

= 720 / 495

= 720

Step2:

LCM(45, 987) = 14805

GCD(45, 987) = ( 45 x 987 ) / 14805

= 45 / 987

= 45

Step3:

LCM(3, 683) = 2049

GCD(3, 683) = ( 3 x 683 ) / 2049

= 3 / 683

= 3

So, Greatest Common Divisor of 720, 495, 987, 683 is 1
