The gcf of two numbers is 170. neither number is divisible by the other. what is the smallest these two numbers could be? (prime

ivanzaharov [21]

Answer:

$340$

Step-by-step explanation:

Given: GCF of two numbers is $170$ . neither number is divisible by the other.

To Find: smallest of these two number.

Solution:

As GCF of two numbers is $170$ , both number are divisible by $170$ .

Prime factor of $170$ $=2\times5\times17$

multiples of $170$ are $1\times2\times5\times17=170$

$2\times2\times5\times17=340$

$3\times2\times5\times17=510$

GCF of all three multiples is $170$ ,

Here $340$ and $510$ are the two multiples whose GCF is $170$ and neither is divisible by other

Hence the smallest of two is $340$ , the answer is $340$
