Given numbers are 217, 183, 455, 310

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 183 are 3 x 61

Prime factors of 455 are 5 x 7 x 13

Prime factors of 310 are 2 x 5 x 31

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

Given numbers are 217, 183, 455, 310

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

Apply this formula for all numbers.

Step1:

LCM(217, 183) = 39711

GCD(217, 183) = ( 217 x 183 ) / 39711

= 217 / 183

= 217

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

So, Greatest Common Divisor of 217, 183, 455, 310 is 1
