Given numbers are 478, 648, 751, 343

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 751 are 751

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 478, 648, 751, 343

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

Apply this formula for all numbers.

Step1:

LCM(478, 648) = 154872

GCD(478, 648) = ( 478 x 648 ) / 154872

= 478 / 648

= 478

Step2:

LCM(2, 751) = 1502

GCD(2, 751) = ( 2 x 751 ) / 1502

= 2 / 751

= 2

Step3:

LCM(1, 343) = 343

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

= 1 / 343

= 1

So, Greatest Common Divisor of 478, 648, 751, 343 is 1
