Given numbers are 415, 646, 612, 344

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 646 are 2 x 17 x 19

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 344 are 2 x 2 x 2 x 43

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

Given numbers are 415, 646, 612, 344

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

Apply this formula for all numbers.

Step1:

LCM(415, 646) = 268090

GCD(415, 646) = ( 415 x 646 ) / 268090

= 415 / 646

= 415

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 344) = 344

GCD(1, 344) = ( 1 x 344 ) / 344

= 1 / 344

= 1

So, Greatest Common Divisor of 415, 646, 612, 344 is 1
