Given numbers are 420, 392, 185, 184

The list of prime factors of all numbers are

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

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

Prime factors of 185 are 5 x 37

Prime factors of 184 are 2 x 2 x 2 x 23

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

Given numbers are 420, 392, 185, 184

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

Apply this formula for all numbers.

Step1:

LCM(420, 392) = 5880

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

= 420 / 392

= 420

Step2:

LCM(28, 185) = 5180

GCD(28, 185) = ( 28 x 185 ) / 5180

= 28 / 185

= 28

Step3:

LCM(1, 184) = 184

GCD(1, 184) = ( 1 x 184 ) / 184

= 1 / 184

= 1

So, Greatest Common Divisor of 420, 392, 185, 184 is 1
