Answer 1

Please think a little with me--

What are the factors of 49 ? Do you know what the word factor means?

It is another word for divisor-- so what number divides exactly into 49?

Think through the multiplication table-- does 49 ever appear???

Yes! 49= 7 times 7.

Now think about 35-- it that number in your multiplication table? What the factors of 35?

HInt: any number that ends in 0 or 5 has 5 for a factor.

So finally, if you have not already figured it out:

35 = 5 times 7.

So the factors are 7 and 7 for 49 and 7 and 5 for 35.

"common" means "in common" - a factor they both share--

What factor do these number have in common??
