Given numbers are 390, 417, 142, 860

The list of prime factors of all numbers are

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

Prime factors of 417 are 3 x 139

Prime factors of 142 are 2 x 71

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

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

Given numbers are 390, 417, 142, 860

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

Apply this formula for all numbers.

Step1:

LCM(390, 417) = 54210

GCD(390, 417) = ( 390 x 417 ) / 54210

= 390 / 417

= 390

Step2:

LCM(3, 142) = 426

GCD(3, 142) = ( 3 x 142 ) / 426

= 3 / 142

= 3

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 390, 417, 142, 860 is 1
