Given numbers are 682, 486, 857, 390

The list of prime factors of all numbers are

Prime factors of 682 are 2 x 11 x 31

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 857 are 857

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 682, 486, 857, 390

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

Apply this formula for all numbers.

Step1:

LCM(682, 486) = 165726

GCD(682, 486) = ( 682 x 486 ) / 165726

= 682 / 486

= 682

Step2:

LCM(2, 857) = 1714

GCD(2, 857) = ( 2 x 857 ) / 1714

= 2 / 857

= 2

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 682, 486, 857, 390 is 1
