Given numbers are 438, 534, 869, 720

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 534 are 2 x 3 x 89

Prime factors of 869 are 11 x 79

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 438, 534, 869, 720

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

Apply this formula for all numbers.

Step1:

LCM(438, 534) = 38982

GCD(438, 534) = ( 438 x 534 ) / 38982

= 438 / 534

= 438

Step2:

LCM(6, 869) = 5214

GCD(6, 869) = ( 6 x 869 ) / 5214

= 6 / 869

= 6

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 438, 534, 869, 720 is 1
