... During each hour, the number of minutes when HH is greater than MM is the same as HH. Combining 8 + 9 + 10 + 11 + 12 + 1 + 2, HH is greater than MM for a total of 53 minutes. 11. 4, 9, 25 and 49 Let N represent any whole number that has exactly 3 factors. Two factors of N are 1 and N. The third fact ...

Decomposing a Number into Prime Factors
... both 0 or if they are divisible by 4 or 2 twice. • A number is divisible by 6 if it is divisible by 2 and by 3 (i.e. if it ends in an even number and if the sum of its digits is divisible by 3). • A number is divisible by 8 if the last 3 digits are all 0 or if the number they form is divisible by 4. ...

Multiplication and Division of Whole Numbers
... To find the factors of a number, try dividing the number by 1, 2, 3, 4, 5, … Those numbers that divide into the number evenly are its factors. Continue this process until the factors start to repeat. A prime number is a natural number greater than one that has exactly two natural number factors, 1 a ...

Properties of Whole Numbers (PDF 108KB)
... Because prime numbers are the building blocks of all whole numbers, any number can be expressed as a product of powers of prime numbers, through multiplication. What does this mean? It means that any and every whole number greater than 1, is either prime or a product of prime numbers; known as the f ...
