Part A: Find the LCM of 8 and 9. Show your work. Part B: Find the GCF of 35 and 63. Show your work.

Part C: Using the GCF you found in Part B, rewrite 35 + 63 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. Show your work.

If I have the option, I will give brainliest to the best response.

A.  72

 B.  7

 C.  35+63 = 7(5+9)

Step-by-step explanation:

A. The two numbers differ by 1, so can have no common factors. Their LCM is their product:

 LCM(8, 9) = 8·9 = 72

__

B. It helps to know your times tables.

 35 = 5·7

 63 = 7·9

The GCF of these numbers is their only common (prime) factor: 7.

 GCF(35, 63) = 7

__

C. Using the distributive property:

 35 +63 = 7·5 +7·9

 35 +63 = 7(5 +9)

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
