Given numbers are 780, 282, 194, 205

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 282 are 2 x 3 x 47

Prime factors of 194 are 2 x 97

Prime factors of 205 are 5 x 41

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

Given numbers are 780, 282, 194, 205

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

Apply this formula for all numbers.

Step1:

LCM(780, 282) = 36660

GCD(780, 282) = ( 780 x 282 ) / 36660

= 780 / 282

= 780

Step2:

LCM(6, 194) = 582

GCD(6, 194) = ( 6 x 194 ) / 582

= 6 / 194

= 6

Step3:

LCM(2, 205) = 410

GCD(2, 205) = ( 2 x 205 ) / 410

= 2 / 205

= 2

So, Greatest Common Divisor of 780, 282, 194, 205 is 1
