Given numbers are 343, 654, 695, 664

The list of prime factors of all numbers are

Prime factors of 343 are 7 x 7 x 7

Prime factors of 654 are 2 x 3 x 109

Prime factors of 695 are 5 x 139

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 343, 654, 695, 664

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

Apply this formula for all numbers.

Step1:

LCM(343, 654) = 224322

GCD(343, 654) = ( 343 x 654 ) / 224322

= 343 / 654

= 343

Step2:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 343, 654, 695, 664 is 1
