Given numbers are 810, 340, 915, 787

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 915 are 3 x 5 x 61

Prime factors of 787 are 787

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

Given numbers are 810, 340, 915, 787

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

Apply this formula for all numbers.

Step1:

LCM(810, 340) = 27540

GCD(810, 340) = ( 810 x 340 ) / 27540

= 810 / 340

= 810

Step2:

LCM(10, 915) = 1830

GCD(10, 915) = ( 10 x 915 ) / 1830

= 10 / 915

= 10

Step3:

LCM(5, 787) = 3935

GCD(5, 787) = ( 5 x 787 ) / 3935

= 5 / 787

= 5

So, Greatest Common Divisor of 810, 340, 915, 787 is 1
