Given numbers are 720, 396, 991, 450

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 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 991 are 991

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 720, 396, 991, 450

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

Apply this formula for all numbers.

Step1:

LCM(720, 396) = 7920

GCD(720, 396) = ( 720 x 396 ) / 7920

= 720 / 396

= 720

Step2:

LCM(36, 991) = 35676

GCD(36, 991) = ( 36 x 991 ) / 35676

= 36 / 991

= 36

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 720, 396, 991, 450 is 1
