Given numbers are 120, 423, 917, 551

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 423 are 3 x 3 x 47

Prime factors of 917 are 7 x 131

Prime factors of 551 are 19 x 29

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

Given numbers are 120, 423, 917, 551

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

Apply this formula for all numbers.

Step1:

LCM(120, 423) = 16920

GCD(120, 423) = ( 120 x 423 ) / 16920

= 120 / 423

= 120

Step2:

LCM(3, 917) = 2751

GCD(3, 917) = ( 3 x 917 ) / 2751

= 3 / 917

= 3

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 120, 423, 917, 551 is 1
