Given numbers are 810, 654, 415, 842

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 654 are 2 x 3 x 109

Prime factors of 415 are 5 x 83

Prime factors of 842 are 2 x 421

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

Given numbers are 810, 654, 415, 842

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

Apply this formula for all numbers.

Step1:

LCM(810, 654) = 88290

GCD(810, 654) = ( 810 x 654 ) / 88290

= 810 / 654

= 810

Step2:

LCM(6, 415) = 2490

GCD(6, 415) = ( 6 x 415 ) / 2490

= 6 / 415

= 6

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 810, 654, 415, 842 is 1
