15 + 5x
'5' is a factor of both '15' & '5' . So take '5' out!!!
Hence
5(3 + x)
What is the factor of q3-q2 plus 2q-2?
q^(3) + q^(2) + 2q + 2
=>
q^(2)(q + 1) + 2(q +1)
(q^(2)+ 2)(q + 1)
Fully factored.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor.
3 is a prime number.
3 is a factor of 9.
3 is a factor of 12.
3 is a common prime factor of 9 and 12.
What are prime common factors?
Example: What are the common prime factors of 120 and 252?
Find the prime factorization of each number by breaking it down into the lowest possible numbers that can be multiplied together to make the original number.
120 = 2x60 = 2x2x30 = 2x2x2x15 = 2x2x2x3x5
252 = 2x126 = 2x2x63 = 2x2x3x21 = 2x2x3x3x7
Notice that there are 2 2's and a 3 in each factorization: the common prime factors are 2, 2, and 3.
What is a common prime factor?
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
Put these numbers in order from greatest to least 0.05 kg and 32 g and 430000 mg?
430,000 mg, 0.05kg, 32 g.
Since 768 is an even number; it ends in '8. It is divislbe by '2'.
Hence
768/2 = 384
Hence
768 = 2 x 384
NO!!!! You have it the wrong way around!!!!
'25' is a multiple of '5'
'5' is a factor of '25'.
twenty-seven
3 x 30 = 90
3 x 3 = 9
90 - 9 = 81 = 3 x (30 - 3) = 3 x 27
What is the prime factorization of 11?
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.
What are the first four multiples of nine?
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
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.
What is the factor of sexual temptation problem among teenagers?
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.
What is the greatest common factor of 36 48 and 30?
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
