Given numbers are 392, 420, 325, 838

The list of prime factors of all numbers are

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Prime factors of 325 are 5 x 5 x 13

Prime factors of 838 are 2 x 419

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

Given numbers are 392, 420, 325, 838

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

Apply this formula for all numbers.

Step1:

LCM(392, 420) = 5880

GCD(392, 420) = ( 392 x 420 ) / 5880

= 392 / 420

= 392

Step2:

LCM(28, 325) = 9100

GCD(28, 325) = ( 28 x 325 ) / 9100

= 28 / 325

= 28

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 392, 420, 325, 838 is 1
