Given numbers are 521, 210, 115, 159

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 115 are 5 x 23

Prime factors of 159 are 3 x 53

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

Given numbers are 521, 210, 115, 159

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

Apply this formula for all numbers.

Step1:

LCM(521, 210) = 109410

GCD(521, 210) = ( 521 x 210 ) / 109410

= 521 / 210

= 521

Step2:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 521, 210, 115, 159 is 1
