Given numbers are 511, 728, 215, 159

The list of prime factors of all numbers are

Prime factors of 511 are 7 x 73

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 215 are 5 x 43

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 511, 728, 215, 159

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

Apply this formula for all numbers.

Step1:

LCM(511, 728) = 53144

GCD(511, 728) = ( 511 x 728 ) / 53144

= 511 / 728

= 511

Step2:

LCM(7, 215) = 1505

GCD(7, 215) = ( 7 x 215 ) / 1505

= 7 / 215

= 7

Step3:

LCM(1, 159) = 159

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

= 1 / 159

= 1

So, Greatest Common Divisor of 511, 728, 215, 159 is 1
