Given numbers are 315, 447, 862, 689

The list of prime factors of all numbers are

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

Prime factors of 447 are 3 x 149

Prime factors of 862 are 2 x 431

Prime factors of 689 are 13 x 53

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

Given numbers are 315, 447, 862, 689

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

Apply this formula for all numbers.

Step1:

LCM(315, 447) = 46935

GCD(315, 447) = ( 315 x 447 ) / 46935

= 315 / 447

= 315

Step2:

LCM(3, 862) = 2586

GCD(3, 862) = ( 3 x 862 ) / 2586

= 3 / 862

= 3

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 315, 447, 862, 689 is 1
