Given numbers are 805, 460, 21, 394

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 21 are 3 x 7

Prime factors of 394 are 2 x 197

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

Given numbers are 805, 460, 21, 394

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

Apply this formula for all numbers.

Step1:

LCM(805, 460) = 3220

GCD(805, 460) = ( 805 x 460 ) / 3220

= 805 / 460

= 805

Step2:

LCM(115, 21) = 2415

GCD(115, 21) = ( 115 x 21 ) / 2415

= 115 / 21

= 115

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 805, 460, 21, 394 is 1
