Factoring and Multiples

Since 768 is an even number; it ends in '8. It is divislbe by '2'.

Hence

768/2 = 384

Hence

768 = 2 x 384

0.2

NO!!!! You have it the wrong way around!!!!

'25' is a multiple of '5'

'5' is a factor of '25'.

The Least Common Multiple (LCM) for 5 6 is 30.

twenty-seven

3 x 30 = 90

3 x 3 = 9

90 - 9 = 81 = 3 x (30 - 3) = 3 x 27

By the fact that it is a PRIME Number, it does NOT factorise, except for itself and '1'.

They named prime numbers because they do factorise.

NB Except for '2' all prime numbers are odd numbers.

However, NOT all odd numbers are prime number.

Odd numbers ending in 1,3,7,& 9. can be prime numbers. Odd numbers ending in '5' are NOT prime number

So to test for a prime number.

If it is EVEN , ending in 0,2,4,6,8 , it is NOT a Prime Number.

It is ends in '5' it is NOT a prime Number.

If the digits sum to '9' it is NOT a Prime Number. e.g. 531 ; 5 + 3 + 1 = 9

So 531/ 9 = 59 So it is NOT a Prime number.

Then divide the given number by '3' or '7', if there isa remainder then it is a prime number.

So 1253

Try '3' = 417 remainder '2'

Try '7' =179 So 1253 is NOT a prime number.

9, 18, 27, 36

If you struggle at the 9 times table, you can think of it like this:

1 times 10 = 10, 10 - 1 = 9

2 times 10 = 20, 20 - 2 = 18

3 times 10 = 30 , 30 - 3 = 27

and so on

YES!!! Because 15 x 2 = 30

1.75 is typically expressed as "one point seventy-five" in a mathematical context. In spoken language, it can also be referred to as "one and three-quarters" when discussing fractions.

1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

1,3,5,15 and 45

The GCF is 5.

The factor of sexual temptation among teenagers often stems from a combination of biological, psychological, and social influences. Hormonal changes during adolescence heighten sexual curiosity and desire, while peer pressure and societal norms can encourage exploration of sexual relationships. Additionally, exposure to sexual content in media and online platforms can further complicate teenagers' understanding of healthy relationships and consent. These factors can lead to risky behaviors and emotional challenges if not addressed through education and open communication.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.

The greatest common factor of 30, 36, and 48 is 6

The LCM of 1 and 7 is 7.

Every number has a square root and cube root.

e.g.

2^(1/2) = 1.414213562.....

2^(1/3) = 1.25992105.....

Both are irrational AND RECUR TO INFINITY.

Similarly every other number.

9x^(2) - 49

Re-write as two squared terms.

(3x)^(2) - 7^(2)

This will factor to

( 3x - 7)(3x + 7)

Note the two different signs.

'3'

3 x 2 = 6

3 x 3 = 9

'3' is a common factor to both multiples, so it is the LCF.

The least common multiple of 3, 4, 5, and 9 is 180.

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.

The most common amount of vagina's is 3 but 4-8 are publicly accepted.

30b^(2) + 48b - 24

Factor out '6'

6(5b^(2) + 8b - 4)

Write down the factors of '5', 5 & 1. and '4' ; 4,1, + 2,2

Select a pair of factors that multiply together and then add to arrive at '8'

Hence (5 x 2) - ( 1 x 2) = 10 - 2 = 8

Open brackets

6(5b 2)(b 2)

Since the '4' is negative aamd the '8' is positive. Then the larger term is positive.

Hence 6(5b - 2)(b + 2)

'23' is a prime number.

In the multiplication tables , up to ten, you will not find it anywhere.

No because all the numbers in a prime factorization must be prime. The number 9 is not prime. It should be 3 *3. same thing with 4, should be 2*2. So what would be a prime factorization is 2x2x2x3x3x5x11.
