Given numbers are 815, 734, 646, 624

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 734 are 2 x 367

Prime factors of 646 are 2 x 17 x 19

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

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

Given numbers are 815, 734, 646, 624

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

Apply this formula for all numbers.

Step1:

LCM(815, 734) = 598210

GCD(815, 734) = ( 815 x 734 ) / 598210

= 815 / 734

= 815

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 815, 734, 646, 624 is 1
