Given numbers are 215, 205, 660, 349

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 205 are 5 x 41

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

Prime factors of 349 are 349

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

Given numbers are 215, 205, 660, 349

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

Apply this formula for all numbers.

Step1:

LCM(215, 205) = 8815

GCD(215, 205) = ( 215 x 205 ) / 8815

= 215 / 205

= 215

Step2:

LCM(5, 660) = 660

GCD(5, 660) = ( 5 x 660 ) / 660

= 5 / 660

= 5

Step3:

LCM(5, 349) = 1745

GCD(5, 349) = ( 5 x 349 ) / 1745

= 5 / 349

= 5

So, Greatest Common Divisor of 215, 205, 660, 349 is 1
