Given numbers are 504, 245, 20, 159

The list of prime factors of all numbers are

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 245 are 5 x 7 x 7

Prime factors of 20 are 2 x 2 x 5

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 504, 245, 20, 159

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

Apply this formula for all numbers.

Step1:

LCM(504, 245) = 17640

GCD(504, 245) = ( 504 x 245 ) / 17640

= 504 / 245

= 504

Step2:

LCM(7, 20) = 140

GCD(7, 20) = ( 7 x 20 ) / 140

= 7 / 20

= 7

Step3:

LCM(1, 159) = 159

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

= 1 / 159

= 1

So, Greatest Common Divisor of 504, 245, 20, 159 is 1
