Presumably, the theory is that it's easier to multiply by small numbers than larger ones. If there's a number that you need multiplied by 18, multiply it by 3, then multiply that total by 3, then multiply that total by 2.
That's an infinite list. 76 and 78 are on it.
If your numbers have no prime factors in common, they are relatively prime.
Prime factors are part of prime factorizations. Prime factorizations help in finding the GCF and LCM of integers. Finding the GCF helps in reducing fractions. Finding the LCM helps in adding and subtracting unlike fractions. Carpenters do this. Chefs do this. It's entirely possible you will have no need of this, but it's better to know something and not need to use it then not know something you need to use. If you have children of your own, you can help them with their math homework.
Prime numbers only have one and themselves as factors.
In this cant
you multiply them together
Either one will work. If you're listing factors, use factors. If you're using prime factorization, use prime factors.
To find the greatest common factor (GCF) of two factors, first list the factors of each number. Then, identify the common factors between them. The GCF is the largest of these common factors. Alternatively, you can use the prime factorization method, where you break down each number into its prime factors and multiply the lowest powers of all common prime factors.
That's an infinite list. 76 and 78 are on it.
Oh honey, let's break it down for you. The factors of 12 are 1, 2, 3, 4, 6, and 12 because they can all divide evenly into 12. Now, the prime factors of 12 are 2 and 3, because those are the prime numbers that multiply together to give you 12. So, there you have it, sweetie!
To find the highest common factor (HCF) of 30, 210, and 700, you can use the prime factorization method. Prime Factorization: Prime factorize each number: 30 = 2 * 3 * 5 210 = 2 * 3 * 5 * 7 700 = 2^2 * 5^2 * 7 Identify Common Prime Factors: Identify the common prime factors among the numbers: 2, 3, 5, and 7. Multiply Common Prime Factors: Multiply the common prime factors: 2 * 3 * 5 * 7 = 210 Therefore, the HCF of 30, 210, and 700 is 210.

Factors OR multiplicands.
The factors of 16 are:1, 2, 4, 8, 16The factors of 20 are:1, 2, 4, 5, 10, 20The common factors are:1, 2, 4The Greatest Common Factor:GCF = 4
Yes. Since 36 x 10 = 360, combine the prime factors of 36 with the prime factors of 10.
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
