Given numbers are 966, 399, 170, 155

The list of prime factors of all numbers are

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 399 are 3 x 7 x 19

Prime factors of 170 are 2 x 5 x 17

Prime factors of 155 are 5 x 31

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

Given numbers are 966, 399, 170, 155

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

Apply this formula for all numbers.

Step1:

LCM(966, 399) = 18354

GCD(966, 399) = ( 966 x 399 ) / 18354

= 966 / 399

= 966

Step2:

LCM(21, 170) = 3570

GCD(21, 170) = ( 21 x 170 ) / 3570

= 21 / 170

= 21

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 966, 399, 170, 155 is 1
