Given numbers are 170, 792, 990, 219

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 219 are 3 x 73

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

Given numbers are 170, 792, 990, 219

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

Apply this formula for all numbers.

Step1:

LCM(170, 792) = 67320

GCD(170, 792) = ( 170 x 792 ) / 67320

= 170 / 792

= 170

Step2:

LCM(2, 990) = 990

GCD(2, 990) = ( 2 x 990 ) / 990

= 2 / 990

= 2

Step3:

LCM(2, 219) = 438

GCD(2, 219) = ( 2 x 219 ) / 438

= 2 / 219

= 2

So, Greatest Common Divisor of 170, 792, 990, 219 is 1
