Given numbers are 170, 891, 945, 716

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Prime factors of 716 are 2 x 2 x 179

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

Given numbers are 170, 891, 945, 716

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

Apply this formula for all numbers.

Step1:

LCM(170, 891) = 151470

GCD(170, 891) = ( 170 x 891 ) / 151470

= 170 / 891

= 170

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 716) = 716

GCD(1, 716) = ( 1 x 716 ) / 716

= 1 / 716

= 1

So, Greatest Common Divisor of 170, 891, 945, 716 is 1
