Given numbers are 723, 175, 406, 420

The list of prime factors of all numbers are

Prime factors of 723 are 3 x 241

Prime factors of 175 are 5 x 5 x 7

Prime factors of 406 are 2 x 7 x 29

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 723, 175, 406, 420

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

Apply this formula for all numbers.

Step1:

LCM(723, 175) = 126525

GCD(723, 175) = ( 723 x 175 ) / 126525

= 723 / 175

= 723

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 723, 175, 406, 420 is 1
