Given numbers are 861, 299, 738, 315

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 299 are 13 x 23

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 315 are 3 x 3 x 5 x 7

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

Given numbers are 861, 299, 738, 315

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

Apply this formula for all numbers.

Step1:

LCM(861, 299) = 257439

GCD(861, 299) = ( 861 x 299 ) / 257439

= 861 / 299

= 861

Step2:

LCM(1, 738) = 738

GCD(1, 738) = ( 1 x 738 ) / 738

= 1 / 738

= 1

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 861, 299, 738, 315 is 1
