Given numbers are 138, 663, 506, 486

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 663 are 3 x 13 x 17

Prime factors of 506 are 2 x 11 x 23

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

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

Given numbers are 138, 663, 506, 486

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

Apply this formula for all numbers.

Step1:

LCM(138, 663) = 30498

GCD(138, 663) = ( 138 x 663 ) / 30498

= 138 / 663

= 138

Step2:

LCM(3, 506) = 1518

GCD(3, 506) = ( 3 x 506 ) / 1518

= 3 / 506

= 3

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 138, 663, 506, 486 is 1
