Given numbers are 120, 295, 409, 891

The list of prime factors of all numbers are

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

Prime factors of 295 are 5 x 59

Prime factors of 409 are 409

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Given numbers are 120, 295, 409, 891

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

Apply this formula for all numbers.

Step1:

LCM(120, 295) = 7080

GCD(120, 295) = ( 120 x 295 ) / 7080

= 120 / 295

= 120

Step2:

LCM(5, 409) = 2045

GCD(5, 409) = ( 5 x 409 ) / 2045

= 5 / 409

= 5

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 120, 295, 409, 891 is 1
