Given numbers are 780, 705, 818, 459

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 705 are 3 x 5 x 47

Prime factors of 818 are 2 x 409

Prime factors of 459 are 3 x 3 x 3 x 17

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

Given numbers are 780, 705, 818, 459

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

Apply this formula for all numbers.

Step1:

LCM(780, 705) = 36660

GCD(780, 705) = ( 780 x 705 ) / 36660

= 780 / 705

= 780

Step2:

LCM(15, 818) = 12270

GCD(15, 818) = ( 15 x 818 ) / 12270

= 15 / 818

= 15

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 780, 705, 818, 459 is 1
