Given numbers are 520, 387, 544, 891

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 387 are 3 x 3 x 43

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Given numbers are 520, 387, 544, 891

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

Apply this formula for all numbers.

Step1:

LCM(520, 387) = 201240

GCD(520, 387) = ( 520 x 387 ) / 201240

= 520 / 387

= 520

Step2:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 520, 387, 544, 891 is 1
