Given numbers are 340, 670, 840, 393

The list of prime factors of all numbers are

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 670 are 2 x 5 x 67

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 393 are 3 x 131

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

Given numbers are 340, 670, 840, 393

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

Apply this formula for all numbers.

Step1:

LCM(340, 670) = 22780

GCD(340, 670) = ( 340 x 670 ) / 22780

= 340 / 670

= 340

Step2:

LCM(10, 840) = 840

GCD(10, 840) = ( 10 x 840 ) / 840

= 10 / 840

= 10

Step3:

LCM(10, 393) = 3930

GCD(10, 393) = ( 10 x 393 ) / 3930

= 10 / 393

= 10

So, Greatest Common Divisor of 340, 670, 840, 393 is 1
