Given numbers are 338, 861, 402, 864

The list of prime factors of all numbers are

Prime factors of 338 are 2 x 13 x 13

Prime factors of 861 are 3 x 7 x 41

Prime factors of 402 are 2 x 3 x 67

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 338, 861, 402, 864

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

Apply this formula for all numbers.

Step1:

LCM(338, 861) = 291018

GCD(338, 861) = ( 338 x 861 ) / 291018

= 338 / 861

= 338

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 338, 861, 402, 864 is 1
