Given numbers are 865, 343, 504, 909

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 343 are 7 x 7 x 7

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 909 are 3 x 3 x 101

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

Given numbers are 865, 343, 504, 909

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

Apply this formula for all numbers.

Step1:

LCM(865, 343) = 296695

GCD(865, 343) = ( 865 x 343 ) / 296695

= 865 / 343

= 865

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 865, 343, 504, 909 is 1
