Given numbers are 390, 860, 195, 492

The list of prime factors of all numbers are

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

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 195 are 3 x 5 x 13

Prime factors of 492 are 2 x 2 x 3 x 41

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

Given numbers are 390, 860, 195, 492

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

Apply this formula for all numbers.

Step1:

LCM(390, 860) = 33540

GCD(390, 860) = ( 390 x 860 ) / 33540

= 390 / 860

= 390

Step2:

LCM(10, 195) = 390

GCD(10, 195) = ( 10 x 195 ) / 390

= 10 / 195

= 10

Step3:

LCM(5, 492) = 2460

GCD(5, 492) = ( 5 x 492 ) / 2460

= 5 / 492

= 5

So, Greatest Common Divisor of 390, 860, 195, 492 is 1
