Given numbers are 840, 239, 423, 544

The list of prime factors of all numbers are

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

Prime factors of 239 are 239

Prime factors of 423 are 3 x 3 x 47

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Given numbers are 840, 239, 423, 544

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

Apply this formula for all numbers.

Step1:

LCM(840, 239) = 200760

GCD(840, 239) = ( 840 x 239 ) / 200760

= 840 / 239

= 840

Step2:

LCM(1, 423) = 423

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

= 1 / 423

= 1

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 840, 239, 423, 544 is 1
