Given numbers are 549, 651, 408, 478

The list of prime factors of all numbers are

Prime factors of 549 are 3 x 3 x 61

Prime factors of 651 are 3 x 7 x 31

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 478 are 2 x 239

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

Given numbers are 549, 651, 408, 478

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

Apply this formula for all numbers.

Step1:

LCM(549, 651) = 119133

GCD(549, 651) = ( 549 x 651 ) / 119133

= 549 / 651

= 549

Step2:

LCM(3, 408) = 408

GCD(3, 408) = ( 3 x 408 ) / 408

= 3 / 408

= 3

Step3:

LCM(3, 478) = 1434

GCD(3, 478) = ( 3 x 478 ) / 1434

= 3 / 478

= 3

So, Greatest Common Divisor of 549, 651, 408, 478 is 1
