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.

A: 8*9 = 72 or 72 because it is the lowest multiple of 8 and 9

B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf = 7 or 7 because 7 is the biggest number that goes into both numbers.

C: 7 (5+9) or 35 is a factored into 7 and 5 and 63 is factored into 7 and 9 and 9 is factored into 3 and 3
