Two numbers are relatively prime or coprime if their only common factor is $1$. In other words, two numbers $x$ and $y$ are {relatively prime} if and only if $GCF(x,y)=1.$ For example, $7$ and $9$ are relatively prime. ...

For example, LCM of 2 & 4 is 4. What is the GCF of 24 and 36? By prime factorisation, we know; Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and 36; Factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24; HCF of (24,36) = 12 What is the formula for HCF and LCM?
Common factors: 1 and 5. Greatest Common Factor (GCF) = 5. This method can be used for finding GCF of three or more numbers as well. It might be difficult to find the greatest common factor by listing factors if the numbers are bigger. In such cases, we use the prime factorization ...
In order to find the Greatest Common Factor or GCF, first all the factors must be known between two numbers. For example: The factors of 12: 1, 2, 3, 4, 6, and 12. The factors of 18: 1, 2, 3, 6, 9, and 18. The common factors between 12 and 18 are 1, 2, 3, and 6...
For example,let’s find the greatest common factor of 90 and 165 using prime factorization. To find the prime factors of 90, divide 90 by 2 to get 45. 2 is a prime number, but 45 can be divided by 5 to get 9. 5 is a prime number, but 9 can be divided by 3 to get 3. ...
In reverse form we can use it for factoring. We can state it in words in this way: ‘‘The difference of two squares can be factored into the sum and difference of those values that were squared.” EXAMPLE 1 Factor. 9 x2-1 We see that the problem is in the form of the difference...
