Given numbers are 690, 493, 447, 631

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 493 are 17 x 29

Prime factors of 447 are 3 x 149

Prime factors of 631 are 631

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

Given numbers are 690, 493, 447, 631

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

Apply this formula for all numbers.

Step1:

LCM(690, 493) = 340170

GCD(690, 493) = ( 690 x 493 ) / 340170

= 690 / 493

= 690

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 690, 493, 447, 631 is 1
