Given numbers are 408, 378, 607, 649

The list of prime factors of all numbers are

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

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

Prime factors of 607 are 607

Prime factors of 649 are 11 x 59

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

Given numbers are 408, 378, 607, 649

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

Apply this formula for all numbers.

Step1:

LCM(408, 378) = 25704

GCD(408, 378) = ( 408 x 378 ) / 25704

= 408 / 378

= 408

Step2:

LCM(6, 607) = 3642

GCD(6, 607) = ( 6 x 607 ) / 3642

= 6 / 607

= 6

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 408, 378, 607, 649 is 1
