Given numbers are 806, 945, 491, 225

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 491 are 491

Prime factors of 225 are 3 x 3 x 5 x 5

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

Given numbers are 806, 945, 491, 225

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

Apply this formula for all numbers.

Step1:

LCM(806, 945) = 761670

GCD(806, 945) = ( 806 x 945 ) / 761670

= 806 / 945

= 806

Step2:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 806, 945, 491, 225 is 1
