Given numbers are 720, 280, 456, 243

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 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 720, 280, 456, 243

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

Apply this formula for all numbers.

Step1:

LCM(720, 280) = 5040

GCD(720, 280) = ( 720 x 280 ) / 5040

= 720 / 280

= 720

Step2:

LCM(40, 456) = 2280

GCD(40, 456) = ( 40 x 456 ) / 2280

= 40 / 456

= 40

Step3:

LCM(8, 243) = 1944

GCD(8, 243) = ( 8 x 243 ) / 1944

= 8 / 243

= 8

So, Greatest Common Divisor of 720, 280, 456, 243 is 1
