Given numbers are 206, 346, 274, 645

The list of prime factors of all numbers are

Prime factors of 206 are 2 x 103

Prime factors of 346 are 2 x 173

Prime factors of 274 are 2 x 137

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 206, 346, 274, 645

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

Apply this formula for all numbers.

Step1:

LCM(206, 346) = 35638

GCD(206, 346) = ( 206 x 346 ) / 35638

= 206 / 346

= 206

Step2:

LCM(2, 274) = 274

GCD(2, 274) = ( 2 x 274 ) / 274

= 2 / 274

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 206, 346, 274, 645 is 1
