Given numbers are 280, 908, 530, 515

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 908 are 2 x 2 x 227

Prime factors of 530 are 2 x 5 x 53

Prime factors of 515 are 5 x 103

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

Given numbers are 280, 908, 530, 515

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

Apply this formula for all numbers.

Step1:

LCM(280, 908) = 63560

GCD(280, 908) = ( 280 x 908 ) / 63560

= 280 / 908

= 280

Step2:

LCM(4, 530) = 1060

GCD(4, 530) = ( 4 x 530 ) / 1060

= 4 / 530

= 4

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 280, 908, 530, 515 is 1
