Given numbers are 390, 803, 285, 836

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 803 are 11 x 73

Prime factors of 285 are 3 x 5 x 19

Prime factors of 836 are 2 x 2 x 11 x 19

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

Given numbers are 390, 803, 285, 836

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

Apply this formula for all numbers.

Step1:

LCM(390, 803) = 313170

GCD(390, 803) = ( 390 x 803 ) / 313170

= 390 / 803

= 390

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

So, Greatest Common Divisor of 390, 803, 285, 836 is 1
