Given numbers are 622, 392, 678, 705

The list of prime factors of all numbers are

Prime factors of 622 are 2 x 311

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 678 are 2 x 3 x 113

Prime factors of 705 are 3 x 5 x 47

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

Given numbers are 622, 392, 678, 705

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

Apply this formula for all numbers.

Step1:

LCM(622, 392) = 121912

GCD(622, 392) = ( 622 x 392 ) / 121912

= 622 / 392

= 622

Step2:

LCM(2, 678) = 678

GCD(2, 678) = ( 2 x 678 ) / 678

= 2 / 678

= 2

Step3:

LCM(2, 705) = 1410

GCD(2, 705) = ( 2 x 705 ) / 1410

= 2 / 705

= 2

So, Greatest Common Divisor of 622, 392, 678, 705 is 1
