Given numbers are 215, 788, 768, 858

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 788 are 2 x 2 x 197

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

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

Given numbers are 215, 788, 768, 858

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

Apply this formula for all numbers.

Step1:

LCM(215, 788) = 169420

GCD(215, 788) = ( 215 x 788 ) / 169420

= 215 / 788

= 215

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 215, 788, 768, 858 is 1
