Given numbers are 842, 723, 578, 630

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 723 are 3 x 241

Prime factors of 578 are 2 x 17 x 17

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 842, 723, 578, 630

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

Apply this formula for all numbers.

Step1:

LCM(842, 723) = 608766

GCD(842, 723) = ( 842 x 723 ) / 608766

= 842 / 723

= 842

Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 842, 723, 578, 630 is 1
