Given numbers are 515, 545, 162, 903

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 545 are 5 x 109

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 903 are 3 x 7 x 43

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

Given numbers are 515, 545, 162, 903

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

Apply this formula for all numbers.

Step1:

LCM(515, 545) = 56135

GCD(515, 545) = ( 515 x 545 ) / 56135

= 515 / 545

= 515

Step2:

LCM(5, 162) = 810

GCD(5, 162) = ( 5 x 162 ) / 810

= 5 / 162

= 5

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 515, 545, 162, 903 is 1
