Given numbers are 153, 282, 806, 420

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

Prime factors of 282 are 2 x 3 x 47

Prime factors of 806 are 2 x 13 x 31

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

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

Given numbers are 153, 282, 806, 420

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

Apply this formula for all numbers.

Step1:

LCM(153, 282) = 14382

GCD(153, 282) = ( 153 x 282 ) / 14382

= 153 / 282

= 153

Step2:

LCM(3, 806) = 2418

GCD(3, 806) = ( 3 x 806 ) / 2418

= 3 / 806

= 3

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 153, 282, 806, 420 is 1
