Given numbers are 783, 204, 798, 490

The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 783, 204, 798, 490

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

Apply this formula for all numbers.

Step1:

LCM(783, 204) = 53244

GCD(783, 204) = ( 783 x 204 ) / 53244

= 783 / 204

= 783

Step2:

LCM(3, 798) = 798

GCD(3, 798) = ( 3 x 798 ) / 798

= 3 / 798

= 3

Step3:

LCM(3, 490) = 1470

GCD(3, 490) = ( 3 x 490 ) / 1470

= 3 / 490

= 3

So, Greatest Common Divisor of 783, 204, 798, 490 is 1
