Given numbers are 865, 300, 523, 648

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 523 are 523

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 865, 300, 523, 648

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

Apply this formula for all numbers.

Step1:

LCM(865, 300) = 51900

GCD(865, 300) = ( 865 x 300 ) / 51900

= 865 / 300

= 865

Step2:

LCM(5, 523) = 2615

GCD(5, 523) = ( 5 x 523 ) / 2615

= 5 / 523

= 5

Step3:

LCM(1, 648) = 648

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

= 1 / 648

= 1

So, Greatest Common Divisor of 865, 300, 523, 648 is 1
