Given numbers are 630, 378, 205, 673

The list of prime factors of all numbers are

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

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 205 are 5 x 41

Prime factors of 673 are 673

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

Given numbers are 630, 378, 205, 673

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

Apply this formula for all numbers.

Step1:

LCM(630, 378) = 1890

GCD(630, 378) = ( 630 x 378 ) / 1890

= 630 / 378

= 630

Step2:

LCM(126, 205) = 25830

GCD(126, 205) = ( 126 x 205 ) / 25830

= 126 / 205

= 126

Step3:

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

= 1 / 673

= 1

So, Greatest Common Divisor of 630, 378, 205, 673 is 1
