Given numbers are 705, 406, 12, 551

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 406 are 2 x 7 x 29

Prime factors of 12 are 2 x 2 x 3

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 705, 406, 12, 551

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

Apply this formula for all numbers.

Step1:

LCM(705, 406) = 286230

GCD(705, 406) = ( 705 x 406 ) / 286230

= 705 / 406

= 705

Step2:

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

= 1 / 12

= 1

Step3:

LCM(1, 551) = 551

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

= 1 / 551

= 1

So, Greatest Common Divisor of 705, 406, 12, 551 is 1
