Given numbers are 530, 504, 345, 280

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 345 are 3 x 5 x 23

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

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

Given numbers are 530, 504, 345, 280

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

Apply this formula for all numbers.

Step1:

LCM(530, 504) = 133560

GCD(530, 504) = ( 530 x 504 ) / 133560

= 530 / 504

= 530

Step2:

LCM(2, 345) = 690

GCD(2, 345) = ( 2 x 345 ) / 690

= 2 / 345

= 2

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 530, 504, 345, 280 is 1
