Given numbers are 834, 440, 639, 486

The list of prime factors of all numbers are

Prime factors of 834 are 2 x 3 x 139

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 834, 440, 639, 486

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

Apply this formula for all numbers.

Step1:

LCM(834, 440) = 183480

GCD(834, 440) = ( 834 x 440 ) / 183480

= 834 / 440

= 834

Step2:

LCM(2, 639) = 1278

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

= 2 / 639

= 2

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 834, 440, 639, 486 is 1
