Given numbers are 515, 180, 486, 455

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 515, 180, 486, 455

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

Apply this formula for all numbers.

Step1:

LCM(515, 180) = 18540

GCD(515, 180) = ( 515 x 180 ) / 18540

= 515 / 180

= 515

Step2:

LCM(5, 486) = 2430

GCD(5, 486) = ( 5 x 486 ) / 2430

= 5 / 486

= 5

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 515, 180, 486, 455 is 1
