The best way to find the GCF of a set of numbers is to break down the numbers to their prime factorization. And to do that we need to do the factor tree. After doing so we get:
28 = 2^2 * 7
98 = 2 * 7^2
154 = 2 * 7 * 11
So now we compare the prime factorization, and here we can see that 2*7 or 14 is shared by all of the numbers. So that is the GCF, 14.

F(28) = {1, 2, 4, 7, 14, 28}
F(98) = {1, 2, 7, 14, 49, 98}
F(154) = {1,2, 7, 14, 77, 154}
GCF of 28, 98, 154 is 14

no one has informed you the tactic. So please enable me clarify so as which you understand the tactic. take the difficulty-loose words in the two(like words) and discover the utmost means/quantity that devided consistent 10 and 30 - 10 means of t t^5 and t^6 - t^5 devides the two means of w w^9 and w^0 so no contribution of w means of z z^4 and z^3 = z^3 multiply all of them 10t^5z^3

14.
To find this answer keep dividing the numbers by 2 and multiply all the 2's that you have divided it by.

Divide it by two and that is it.
