3. Look at Square Roots:
Check numbers up to the square root of 90 for potential factors.
Include Negative Factors: Always include the negative counterparts for each positive factor.
Prime Factorization Method
Prime factorization involves deconstructing a composite number to its prime components, the fundamental prime numbers that, when multiplied, reconstruct the original number.
Prime factorization involves breaking down a number into its most minor prime number factors. The process for 90 is as follows:
1. Start with the Smallest Prime Number:
Begin with the smallest prime number that divides 90, which is 2.
2. Continue Dividing:
Divide 90 by 2 to get 45, then proceed with the following smallest prime number, 3. Keep dividing until only prime numbers remain.
3. List the Prime Factors:
The prime factorization of 90 is 2×32×5, with 2, 3, and 5 being prime numbers.
Summary
This comprehensive guide gives a clear understanding of the factors of 90. Discover how pairs like 1 and 90, 2 and 45, or 3 and 30, along with their negative counterparts, make up the structure of 90. Learn to identify these factors and understand the prime factorization of 90 as 2×32×5, which is essential for those interested in mathematics.
They not only deepen your mathematical understanding but also sharpen your problem-solving skills. Whether you’re in the classroom or facing real-world mathematical challenges, mastering these methods will undoubtedly prove beneficial.
