Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 849, 393, 672, 680

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

Apply this formula for all numbers.

Step1:

LCM(849, 393) = 111219

GCD(849, 393) = ( 849 x 393 ) / 111219

= 849 / 393

= 849

Step2:

LCM(3, 672) = 672

GCD(3, 672) = ( 3 x 672 ) / 672

= 3 / 672

= 3

Step3:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

So, Greatest Common Divisor of 849, 393, 672, 680 is 1
