3 <p>Factors are the ‘building blocks’ of a number. They are the numbers that can be multiplied together to reach the number you started with. 137 is an interesting number. It is large enough to make you think, but simple enough to learn if you know a few tricks. Let’s dive into it!</p>

4 <h2>What are the factors of 137?</h2>

5 <p>Factors are<a>whole numbers</a>that, when multiplied, the<a>product</a>is equal to 137. </p>

6 <p>137 is a<a>prime number</a>, its only<a>factors</a>are 1 and 137. For every factor, there is a corresponding negative factor, for 137, the negative factors -1, -137. </p>

7 <h2>How to find the factors of 137?</h2>

8 <p>There are various methods we apply to find the factors<a>of</a>any<a>number</a>. Few of them are listed here; <a>multiplication</a>method,<a>division</a>method,<a>prime factors</a>and prime factorization and<a>factor tree</a>method. These are explained in detail below, let’s learn ! </p>

9 <h3>Finding Factors Using Multiplication</h3>

10 <p>Step 1: Find all pairs of numbers whose product is 137. </p>

11 <p>Step 2: All the pairs found represent the factors of 137. </p>

12 <p>137 is a prime number. The only pair of numbers whose product is 137 is 1×137=137. </p>

13 <p>The factors of 137 are 1 and 137 only. </p>

16 <h3>Finding Factors by Division Method</h3>

15 <h3>Finding Factors by Division Method</h3>

17 <p><strong>Step 1:</strong>Start by dividing 137 with the smallest number, and check the remainders. </p>

16 <p><strong>Step 1:</strong>Start by dividing 137 with the smallest number, and check the remainders. </p>

18 <p><strong>Step 2:</strong>137 is prime, therefore the only divisors it has are 1 and 137. Any number that is further checked for divisibility leaves behind a<a>remainder</a>.</p>

29 <h3>Problem 1</h3>

30 <p>Is 137 divisible by 4?</p>

31 <p>Okay, lets begin</p>

32 <p>Use the divisibility rule for 4, which states that a number is divisible by 4 if its last two digits form a number divisible by 4.</p>

33 <p>The last two digits of 137 are 37.</p>

34 <p>Since 37 ÷ 4 = 9.25 (not a whole number), 137 is not divisible by 4. </p>

35 <h3>Explanation</h3>

36 <p>This problem helps to confirm that 137 does not have 4 as a factor. By using divisibility rules, we can quickly determine if a number has other possible factors without performing long division.</p>

37 <p>Well explained 👍</p>

38 <h3>Problem 2</h3>

39 <p>Verify if any number multiplied by itself results in 137.</p>

40 <p>Okay, lets begin</p>

41 <p>Take the square root of 137 to see if it is a perfect square: 137≈11.7</p>

42 <p>Since 11.7 is not a whole number, no integer multiplied by itself equals 137. </p>

43 <h3>Explanation</h3>

44 <p> If a number is a perfect square, it has an integer as its square root, which would mean it could be factored into two equal whole numbers. Here, 137 is not a perfect square, so it cannot be expressed as a product of any number with itself. </p>

45 <p>Well explained 👍</p>

46 <h3>Problem 3</h3>

47 <p>Can 137 be written as the sum of two factors?</p>

48 <p>Okay, lets begin</p>

49 <p>Since 137 is prime, its only factors are 1 and 137.</p>

50 <p>Adding these two factors gives: 1+137=138</p>

51 <p>Therefore, 137 cannot be written as the sum of two of its factors. </p>

52 <h3>Explanation</h3>

53 <p>With prime numbers, this kind of sum isn’t possible because they only have two factors. For non-prime numbers, however, this sum could sometimes match the number itself or another factor. </p>

54 <p>Well explained 👍</p>
