Given numbers are 170, 649, 217, 234

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 649 are 11 x 59

Prime factors of 217 are 7 x 31

Prime factors of 234 are 2 x 3 x 3 x 13

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

Given numbers are 170, 649, 217, 234

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

Apply this formula for all numbers.

Step1:

LCM(170, 649) = 110330

GCD(170, 649) = ( 170 x 649 ) / 110330

= 170 / 649

= 170

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

Step3:

LCM(1, 234) = 234

GCD(1, 234) = ( 1 x 234 ) / 234

= 1 / 234

= 1

So, Greatest Common Divisor of 170, 649, 217, 234 is 1
