Given numbers are 123, 981, 160, 672

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 981 are 3 x 3 x 109

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

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

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

Given numbers are 123, 981, 160, 672

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

Apply this formula for all numbers.

Step1:

LCM(123, 981) = 40221

GCD(123, 981) = ( 123 x 981 ) / 40221

= 123 / 981

= 123

Step2:

LCM(3, 160) = 480

GCD(3, 160) = ( 3 x 160 ) / 480

= 3 / 160

= 3

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 123, 981, 160, 672 is 1
