Given numbers are 298, 840, 865, 712

The list of prime factors of all numbers are

Prime factors of 298 are 2 x 149

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 865 are 5 x 173

Prime factors of 712 are 2 x 2 x 2 x 89

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

Given numbers are 298, 840, 865, 712

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

Apply this formula for all numbers.

Step1:

LCM(298, 840) = 125160

GCD(298, 840) = ( 298 x 840 ) / 125160

= 298 / 840

= 298

Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

Step3:

LCM(1, 712) = 712

GCD(1, 712) = ( 1 x 712 ) / 712

= 1 / 712

= 1

So, Greatest Common Divisor of 298, 840, 865, 712 is 1
