Given numbers are 441, 423, 156, 124

The list of prime factors of all numbers are

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 423 are 3 x 3 x 47

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 441, 423, 156, 124

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

Apply this formula for all numbers.

Step1:

LCM(441, 423) = 20727

GCD(441, 423) = ( 441 x 423 ) / 20727

= 441 / 423

= 441

Step2:

LCM(9, 156) = 468

GCD(9, 156) = ( 9 x 156 ) / 468

= 9 / 156

= 9

Step3:

LCM(3, 124) = 372

GCD(3, 124) = ( 3 x 124 ) / 372

= 3 / 124

= 3

So, Greatest Common Divisor of 441, 423, 156, 124 is 1
