Given numbers are 438, 264, 802, 639

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

Prime factors of 802 are 2 x 401

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 438, 264, 802, 639

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

Apply this formula for all numbers.

Step1:

LCM(438, 264) = 19272

GCD(438, 264) = ( 438 x 264 ) / 19272

= 438 / 264

= 438

Step2:

LCM(6, 802) = 2406

GCD(6, 802) = ( 6 x 802 ) / 2406

= 6 / 802

= 6

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 438, 264, 802, 639 is 1
