Given numbers are 340, 544, 243, 420

The list of prime factors of all numbers are

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

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 340, 544, 243, 420

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

Apply this formula for all numbers.

Step1:

LCM(340, 544) = 2720

GCD(340, 544) = ( 340 x 544 ) / 2720

= 340 / 544

= 340

Step2:

LCM(68, 243) = 16524

GCD(68, 243) = ( 68 x 243 ) / 16524

= 68 / 243

= 68

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 340, 544, 243, 420 is 1
