Given numbers are 170, 172, 191, 784

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 172 are 2 x 2 x 43

Prime factors of 191 are 191

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 170, 172, 191, 784

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

Apply this formula for all numbers.

Step1:

LCM(170, 172) = 14620

GCD(170, 172) = ( 170 x 172 ) / 14620

= 170 / 172

= 170

Step2:

LCM(2, 191) = 382

GCD(2, 191) = ( 2 x 191 ) / 382

= 2 / 191

= 2

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 170, 172, 191, 784 is 1
