Given numbers are 423, 730, 120, 791

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 730 are 2 x 5 x 73

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 791 are 7 x 113

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

Given numbers are 423, 730, 120, 791

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

Apply this formula for all numbers.

Step1:

LCM(423, 730) = 308790

GCD(423, 730) = ( 423 x 730 ) / 308790

= 423 / 730

= 423

Step2:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 423, 730, 120, 791 is 1
