Given numbers are 623, 445, 701, 408

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 445 are 5 x 89

Prime factors of 701 are 701

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 623, 445, 701, 408

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

Apply this formula for all numbers.

Step1:

LCM(623, 445) = 3115

GCD(623, 445) = ( 623 x 445 ) / 3115

= 623 / 445

= 623

Step2:

LCM(89, 701) = 62389

GCD(89, 701) = ( 89 x 701 ) / 62389

= 89 / 701

= 89

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 623, 445, 701, 408 is 1
