Given numbers are 305, 515, 855, 746

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 515 are 5 x 103

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 746 are 2 x 373

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

Given numbers are 305, 515, 855, 746

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

Apply this formula for all numbers.

Step1:

LCM(305, 515) = 31415

GCD(305, 515) = ( 305 x 515 ) / 31415

= 305 / 515

= 305

Step2:

LCM(5, 855) = 855

GCD(5, 855) = ( 5 x 855 ) / 855

= 5 / 855

= 5

Step3:

LCM(5, 746) = 3730

GCD(5, 746) = ( 5 x 746 ) / 3730

= 5 / 746

= 5

So, Greatest Common Divisor of 305, 515, 855, 746 is 1
