Use the method of dividing by prime factors to find the greatest common factor of 140 and 350.
Natali5045456 [20]

140 = 2*2*5*7

350 = 2*5*5*7


now, let's notice, the 2, 5 and 7 are <u>repeated on both</u>, so we'll use them once, and then we add the <u>non-repeated</u> part to it to get the GCF.

(2*5*7)*2*5  <----- that's the GCF ------> 700.

Find the number that completes the equation.
Alja [10]
What you have to do is multiply 5 on each sides on the equation. Next, you cross out the 2 gives on the left side. Bring down the 6+y and 6 times 5 equals 30. So your equation would be 6+y=30. Then, you subtract 6 from both sides and cross out the 6’s on the left side... Bring down your “y” and 30-6=24. So y=24
