Given numbers are 824, 342, 801, 639

The list of prime factors of all numbers are

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 801 are 3 x 3 x 89

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 824, 342, 801, 639

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

Apply this formula for all numbers.

Step1:

LCM(824, 342) = 140904

GCD(824, 342) = ( 824 x 342 ) / 140904

= 824 / 342

= 824

Step2:

LCM(2, 801) = 1602

GCD(2, 801) = ( 2 x 801 ) / 1602

= 2 / 801

= 2

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 824, 342, 801, 639 is 1
