Given numbers are 723, 803, 216, 646

The list of prime factors of all numbers are

Prime factors of 723 are 3 x 241

Prime factors of 803 are 11 x 73

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 723, 803, 216, 646

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

Apply this formula for all numbers.

Step1:

LCM(723, 803) = 580569

GCD(723, 803) = ( 723 x 803 ) / 580569

= 723 / 803

= 723

Step2:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 723, 803, 216, 646 is 1
