Given numbers are 818, 702, 645, 343

The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 343 are 7 x 7 x 7

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

Given numbers are 818, 702, 645, 343

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

Apply this formula for all numbers.

Step1:

LCM(818, 702) = 287118

GCD(818, 702) = ( 818 x 702 ) / 287118

= 818 / 702

= 818

Step2:

LCM(2, 645) = 1290

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

= 2 / 645

= 2

Step3:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

So, Greatest Common Divisor of 818, 702, 645, 343 is 1
