Given numbers are 447, 704, 686, 666

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 447, 704, 686, 666

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

Apply this formula for all numbers.

Step1:

LCM(447, 704) = 314688

GCD(447, 704) = ( 447 x 704 ) / 314688

= 447 / 704

= 447

Step2:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 447, 704, 686, 666 is 1
