Given numbers are 806, 856, 945, 153

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 856 are 2 x 2 x 2 x 107

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

Prime factors of 153 are 3 x 3 x 17

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

Given numbers are 806, 856, 945, 153

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

Apply this formula for all numbers.

Step1:

LCM(806, 856) = 344968

GCD(806, 856) = ( 806 x 856 ) / 344968

= 806 / 856

= 806

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

So, Greatest Common Divisor of 806, 856, 945, 153 is 1
