Given numbers are 669, 164, 831, 630

The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

Prime factors of 164 are 2 x 2 x 41

Prime factors of 831 are 3 x 277

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 669, 164, 831, 630

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

Apply this formula for all numbers.

Step1:

LCM(669, 164) = 109716

GCD(669, 164) = ( 669 x 164 ) / 109716

= 669 / 164

= 669

Step2:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 669, 164, 831, 630 is 1
