Given numbers are 624, 455, 343

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 455 are 5 x 7 x 13

Prime factors of 343 are 7 x 7 x 7

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

Given numbers are 624, 455, 343

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

Apply this formula for all numbers.

Step1:

LCM(624, 455) = 21840

GCD(624, 455) = ( 624 x 455 ) / 21840

= 624 / 455

= 624

Step2:

LCM(13, 343) = 4459

GCD(13, 343) = ( 13 x 343 ) / 4459

= 13 / 343

= 13

So, Greatest Common Divisor of 624, 455, 343 is 1
