Given numbers are 624, 406, 778, 419

The list of prime factors of all numbers are

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 406 are 2 x 7 x 29

Prime factors of 778 are 2 x 389

Prime factors of 419 are 419

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

Given numbers are 624, 406, 778, 419

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

Apply this formula for all numbers.

Step1:

LCM(624, 406) = 126672

GCD(624, 406) = ( 624 x 406 ) / 126672

= 624 / 406

= 624

Step2:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

Step3:

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

= 2 / 419

= 2

So, Greatest Common Divisor of 624, 406, 778, 419 is 1
