Given numbers are 326, 402, 723, 720

The list of prime factors of all numbers are

Prime factors of 326 are 2 x 163

Prime factors of 402 are 2 x 3 x 67

Prime factors of 723 are 3 x 241

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 326, 402, 723, 720

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

Apply this formula for all numbers.

Step1:

LCM(326, 402) = 65526

GCD(326, 402) = ( 326 x 402 ) / 65526

= 326 / 402

= 326

Step2:

LCM(2, 723) = 1446

GCD(2, 723) = ( 2 x 723 ) / 1446

= 2 / 723

= 2

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 326, 402, 723, 720 is 1
