Given numbers are 830, 416, 123, 120

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 123 are 3 x 41

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 830, 416, 123, 120

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

Apply this formula for all numbers.

Step1:

LCM(830, 416) = 172640

GCD(830, 416) = ( 830 x 416 ) / 172640

= 830 / 416

= 830

Step2:

LCM(2, 123) = 246

GCD(2, 123) = ( 2 x 123 ) / 246

= 2 / 123

= 2

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 830, 416, 123, 120 is 1
