Given numbers are 386, 714, 831, 978

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 714 are 2 x 3 x 7 x 17

Prime factors of 831 are 3 x 277

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 386, 714, 831, 978

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

Apply this formula for all numbers.

Step1:

LCM(386, 714) = 137802

GCD(386, 714) = ( 386 x 714 ) / 137802

= 386 / 714

= 386

Step2:

LCM(2, 831) = 1662

GCD(2, 831) = ( 2 x 831 ) / 1662

= 2 / 831

= 2

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 386, 714, 831, 978 is 1
