Given numbers are 530, 406, 343, 378

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 406 are 2 x 7 x 29

Prime factors of 343 are 7 x 7 x 7

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 530, 406, 343, 378

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

Apply this formula for all numbers.

Step1:

LCM(530, 406) = 107590

GCD(530, 406) = ( 530 x 406 ) / 107590

= 530 / 406

= 530

Step2:

LCM(2, 343) = 686

GCD(2, 343) = ( 2 x 343 ) / 686

= 2 / 343

= 2

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 530, 406, 343, 378 is 1
