Literacy Research Memory Skill Practice Stretch! Prime, Factor, Multiple, Highest Common Factor, Lowest Common Multiple What are perfect numbers? Find the only 3 examples below 500 Make sure you can explain what prime numbers and factors are. Skill Practice Stretch! 1) Complete the prime factor trees for 56 and 84 I think of 2 numbers. The Highest Common Factor of these numbers is 12. Give 3 possible numbers I could be thinking of. The Lowest Common Multiple of my numbers is 1260. There are 3 possible pairs of numbers. What are they? 56 84 2) What is the HCF and the LCM of 36 and 50? 3) Which number can be written as 3 x 3 x 5 x 7? 4) Bread rolls are sold in packs of 36. Burgers are sold in packs of 24. How many packs of each must be ordered so that there are the same number of burgers and bread rolls?
