Given numbers are 874, 342, 815, 648

The list of prime factors of all numbers are

Prime factors of 874 are 2 x 19 x 23

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 815 are 5 x 163

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 874, 342, 815, 648

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

Apply this formula for all numbers.

Step1:

LCM(874, 342) = 7866

GCD(874, 342) = ( 874 x 342 ) / 7866

= 874 / 342

= 874

Step2:

LCM(38, 815) = 30970

GCD(38, 815) = ( 38 x 815 ) / 30970

= 38 / 815

= 38

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 874, 342, 815, 648 is 1
