Given numbers are 307, 923, 458, 840

The list of prime factors of all numbers are

Prime factors of 307 are 307

Prime factors of 923 are 13 x 71

Prime factors of 458 are 2 x 229

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 307, 923, 458, 840

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

Apply this formula for all numbers.

Step1:

LCM(307, 923) = 283361

GCD(307, 923) = ( 307 x 923 ) / 283361

= 307 / 923

= 307

Step2:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 307, 923, 458, 840 is 1
