Given numbers are 530, 120, 244, 687

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 244 are 2 x 2 x 61

Prime factors of 687 are 3 x 229

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

Given numbers are 530, 120, 244, 687

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

Apply this formula for all numbers.

Step1:

LCM(530, 120) = 6360

GCD(530, 120) = ( 530 x 120 ) / 6360

= 530 / 120

= 530

Step2:

LCM(10, 244) = 1220

GCD(10, 244) = ( 10 x 244 ) / 1220

= 10 / 244

= 10

Step3:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2

So, Greatest Common Divisor of 530, 120, 244, 687 is 1
