Given numbers are 408, 803, 830, 457

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 803 are 11 x 73

Prime factors of 830 are 2 x 5 x 83

Prime factors of 457 are 457

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

Given numbers are 408, 803, 830, 457

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

Apply this formula for all numbers.

Step1:

LCM(408, 803) = 327624

GCD(408, 803) = ( 408 x 803 ) / 327624

= 408 / 803

= 408

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 408, 803, 830, 457 is 1
