Given numbers are 705, 638, 178, 500

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 638 are 2 x 11 x 29

Prime factors of 178 are 2 x 89

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

Given numbers are 705, 638, 178, 500

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

Apply this formula for all numbers.

Step1:

LCM(705, 638) = 449790

GCD(705, 638) = ( 705 x 638 ) / 449790

= 705 / 638

= 705

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

Step3:

LCM(1, 500) = 500

GCD(1, 500) = ( 1 x 500 ) / 500

= 1 / 500

= 1

So, Greatest Common Divisor of 705, 638, 178, 500 is 1
