Given numbers are 515, 720, 407, 906

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 407 are 11 x 37

Prime factors of 906 are 2 x 3 x 151

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

Given numbers are 515, 720, 407, 906

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

Apply this formula for all numbers.

Step1:

LCM(515, 720) = 74160

GCD(515, 720) = ( 515 x 720 ) / 74160

= 515 / 720

= 515

Step2:

LCM(5, 407) = 2035

GCD(5, 407) = ( 5 x 407 ) / 2035

= 5 / 407

= 5

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 515, 720, 407, 906 is 1
