Given numbers are 686, 438, 330, 201

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 438 are 2 x 3 x 73

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 201 are 3 x 67

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

Given numbers are 686, 438, 330, 201

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

Apply this formula for all numbers.

Step1:

LCM(686, 438) = 150234

GCD(686, 438) = ( 686 x 438 ) / 150234

= 686 / 438

= 686

Step2:

LCM(2, 330) = 330

GCD(2, 330) = ( 2 x 330 ) / 330

= 2 / 330

= 2

Step3:

LCM(2, 201) = 402

GCD(2, 201) = ( 2 x 201 ) / 402

= 2 / 201

= 2

So, Greatest Common Divisor of 686, 438, 330, 201 is 1
