Given numbers are 273, 328, 423, 840

The list of prime factors of all numbers are

Prime factors of 273 are 3 x 7 x 13

Prime factors of 328 are 2 x 2 x 2 x 41

Prime factors of 423 are 3 x 3 x 47

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 273, 328, 423, 840

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

Apply this formula for all numbers.

Step1:

LCM(273, 328) = 89544

GCD(273, 328) = ( 273 x 328 ) / 89544

= 273 / 328

= 273

Step2:

LCM(1, 423) = 423

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

= 1 / 423

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 273, 328, 423, 840 is 1
