Given numbers are 830, 405, 603, 128

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 603 are 3 x 3 x 67

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 830, 405, 603, 128

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, 603) = 3015

GCD(5, 603) = ( 5 x 603 ) / 3015

= 5 / 603

= 5

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 830, 405, 603, 128 is 1
