Given numbers are 780, 782, 439, 286

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 782 are 2 x 17 x 23

Prime factors of 439 are 439

Prime factors of 286 are 2 x 11 x 13

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

Given numbers are 780, 782, 439, 286

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

Apply this formula for all numbers.

Step1:

LCM(780, 782) = 304980

GCD(780, 782) = ( 780 x 782 ) / 304980

= 780 / 782

= 780

Step2:

LCM(2, 439) = 878

GCD(2, 439) = ( 2 x 439 ) / 878

= 2 / 439

= 2

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 780, 782, 439, 286 is 1
