Given numbers are 830, 405, 984, 380

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 984 are 2 x 2 x 2 x 3 x 41

Prime factors of 380 are 2 x 2 x 5 x 19

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

Given numbers are 830, 405, 984, 380

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

Apply this formula for all numbers.

Step1:

LCM(830, 405) = 67230

GCD(830, 405) = ( 830 x 405 ) / 67230

= 830 / 405

= 830

Step2:

LCM(5, 984) = 4920

GCD(5, 984) = ( 5 x 984 ) / 4920

= 5 / 984

= 5

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 830, 405, 984, 380 is 1
