Given numbers are 420, 384, 860, 841

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 841 are 29 x 29

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

Given numbers are 420, 384, 860, 841

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

Apply this formula for all numbers.

Step1:

LCM(420, 384) = 13440

GCD(420, 384) = ( 420 x 384 ) / 13440

= 420 / 384

= 420

Step2:

LCM(12, 860) = 2580

GCD(12, 860) = ( 12 x 860 ) / 2580

= 12 / 860

= 12

Step3:

LCM(4, 841) = 3364

GCD(4, 841) = ( 4 x 841 ) / 3364

= 4 / 841

= 4

So, Greatest Common Divisor of 420, 384, 860, 841 is 1
