Given numbers are 905, 423, 660, 931

The list of prime factors of all numbers are

Prime factors of 905 are 5 x 181

Prime factors of 423 are 3 x 3 x 47

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 931 are 7 x 7 x 19

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

Given numbers are 905, 423, 660, 931

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

Apply this formula for all numbers.

Step1:

LCM(905, 423) = 382815

GCD(905, 423) = ( 905 x 423 ) / 382815

= 905 / 423

= 905

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 905, 423, 660, 931 is 1
