Given numbers are 520, 315, 891, 505

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 315 are 3 x 3 x 5 x 7

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

Prime factors of 505 are 5 x 101

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

Given numbers are 520, 315, 891, 505

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

Apply this formula for all numbers.

Step1:

LCM(520, 315) = 32760

GCD(520, 315) = ( 520 x 315 ) / 32760

= 520 / 315

= 520

Step2:

LCM(5, 891) = 4455

GCD(5, 891) = ( 5 x 891 ) / 4455

= 5 / 891

= 5

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 520, 315, 891, 505 is 1
