Given numbers are 440, 862, 530, 423

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 862 are 2 x 431

Prime factors of 530 are 2 x 5 x 53

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 440, 862, 530, 423

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

Apply this formula for all numbers.

Step1:

LCM(440, 862) = 189640

GCD(440, 862) = ( 440 x 862 ) / 189640

= 440 / 862

= 440

Step2:

LCM(2, 530) = 530

GCD(2, 530) = ( 2 x 530 ) / 530

= 2 / 530

= 2

Step3:

LCM(2, 423) = 846

GCD(2, 423) = ( 2 x 423 ) / 846

= 2 / 423

= 2

So, Greatest Common Divisor of 440, 862, 530, 423 is 1
