Given numbers are 680, 379, 858, 521

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 379 are 379

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 521 are 521

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

Given numbers are 680, 379, 858, 521

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

Apply this formula for all numbers.

Step1:

LCM(680, 379) = 257720

GCD(680, 379) = ( 680 x 379 ) / 257720

= 680 / 379

= 680

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 680, 379, 858, 521 is 1
