Given numbers are 646, 663, 486, 790

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 663 are 3 x 13 x 17

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

Prime factors of 790 are 2 x 5 x 79

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

Given numbers are 646, 663, 486, 790

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

Apply this formula for all numbers.

Step1:

LCM(646, 663) = 25194

GCD(646, 663) = ( 646 x 663 ) / 25194

= 646 / 663

= 646

Step2:

LCM(17, 486) = 8262

GCD(17, 486) = ( 17 x 486 ) / 8262

= 17 / 486

= 17

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 646, 663, 486, 790 is 1
