Given numbers are 678, 732, 530, 215

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 732 are 2 x 2 x 3 x 61

Prime factors of 530 are 2 x 5 x 53

Prime factors of 215 are 5 x 43

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

Given numbers are 678, 732, 530, 215

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

Apply this formula for all numbers.

Step1:

LCM(678, 732) = 82716

GCD(678, 732) = ( 678 x 732 ) / 82716

= 678 / 732

= 678

Step2:

LCM(6, 530) = 1590

GCD(6, 530) = ( 6 x 530 ) / 1590

= 6 / 530

= 6

Step3:

LCM(2, 215) = 430

GCD(2, 215) = ( 2 x 215 ) / 430

= 2 / 215

= 2

So, Greatest Common Divisor of 678, 732, 530, 215 is 1
