Given numbers are 820, 918, 486, 855

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 820, 918, 486, 855

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

Apply this formula for all numbers.

Step1:

LCM(820, 918) = 376380

GCD(820, 918) = ( 820 x 918 ) / 376380

= 820 / 918

= 820

Step2:

LCM(2, 486) = 486

GCD(2, 486) = ( 2 x 486 ) / 486

= 2 / 486

= 2

Step3:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

So, Greatest Common Divisor of 820, 918, 486, 855 is 1
