Given numbers are 343, 528, 779, 642

The list of prime factors of all numbers are

Prime factors of 343 are 7 x 7 x 7

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 779 are 19 x 41

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 343, 528, 779, 642

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

Apply this formula for all numbers.

Step1:

LCM(343, 528) = 181104

GCD(343, 528) = ( 343 x 528 ) / 181104

= 343 / 528

= 343

Step2:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 343, 528, 779, 642 is 1
