Given numbers are 147, 168, 920, 423

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 147, 168, 920, 423

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

Apply this formula for all numbers.

Step1:

LCM(147, 168) = 1176

GCD(147, 168) = ( 147 x 168 ) / 1176

= 147 / 168

= 147

Step2:

LCM(21, 920) = 19320

GCD(21, 920) = ( 21 x 920 ) / 19320

= 21 / 920

= 21

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 147, 168, 920, 423 is 1
