Given numbers are 670, 631, 855, 863

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 631 are 631

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 863 are 863

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

Given numbers are 670, 631, 855, 863

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

Apply this formula for all numbers.

Step1:

LCM(670, 631) = 422770

GCD(670, 631) = ( 670 x 631 ) / 422770

= 670 / 631

= 670

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 670, 631, 855, 863 is 1
