Given numbers are 631, 705, 840, 178

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 705 are 3 x 5 x 47

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 178 are 2 x 89

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

Given numbers are 631, 705, 840, 178

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

Apply this formula for all numbers.

Step1:

LCM(631, 705) = 444855

GCD(631, 705) = ( 631 x 705 ) / 444855

= 631 / 705

= 631

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 631, 705, 840, 178 is 1
