as a product of its prime factors: 2*3*5*7 = 210
Half of 420 is 210. To find half of a number, you divide it by 2. In this case, 420 divided by 2 equals 210. This is because division is the inverse operation of multiplication, and dividing by 2 is the same as multiplying by 0.5.
1 x 210, 2 x 105, 3 x 70, 5 x 42, 6 x 35, 7 x 30, 10 x 21, 14 x 15.
prime numbers.
It's the prime factorization: 2 x 2 x 2 x 3 x 5 = 120 Also note that you can always add x1x1x1... but these are not included in the prime factorization since 1 is not prime.

2x2x3x3x5This question is equivalent to asking for the prime factorization:180 = 10x18 =(2x5)x(2x9) = 2x5x2x(3x3) = 2x2x3x3x5
Factor strings are multiplication sentences. You can take any factor pair, put a multiplication symbol between them and you have a factor string. The longest factor string for any composite number is the prime factorization. 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. And the longest factor string.
0, 21, 42, 63, 84, 105, 126, 147, 168, 189, 210 etc.
A combination of multiplication and sums is called arithmetic. Subtraction and division are also included in arithmetic.

A factor string is a multiplication sentence. The smallest are the factor pairs, the largest is the prime factorization. All composite numbers can be expressed as unique products of prime numbers.
