Step 2: Circle the smallest number which is 2 in the table. Cross all the multiples of 2 until 50. This will eliminate all the even numbers (which are multiples of 2), and are not prime as they have more than 2 factors.The multiples of 2 that are eliminated from the table are as follows: 4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48, and 50.

There are a total of 50 odd numbers, so n = 50. So, by substituting the values, we get, S = n/2(first odd number + last odd number) S = 50/2(1 + 99) S = 25 × 100. S = 2500. So, the sum of all odd numbers from 1 to 100 is 2500. Even and Odd Numbers 1 to 100. There are 50 even numbers and 50 odd numbers from 1 to 100.

Other methods that can be used to calculate squares from 1 to 50: Finding Square by Column Method; Finding Squares by Diagonal Method; If you Take Squares from 1 to 50, how many of them will be Even Numbers? The even numbers between 1 to 50 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50. Since ...

The commonly used methods to find the LCM of 30 and 40 are: Division Method; Listing Multiples; Prime Factorization Method; If the LCM of 40 and 30 is 120, Find its GCF. LCM(40, 30) × GCF(40, 30) = 40 × 30 Since the LCM of 40 and 30 = 120 ⇒ 120 × GCF(40, 30) = 1200 Therefore, the GCF (greatest common factor) = 1200/120 = 10.

Using the tables from 11 to 30, find the value of 28 times 8. From the table of 28, we know that 28 times 8 = 28 × 8 = 224. How to Learn 12 to 30 Tables easily? 12 to 30 tables can be learned easily using a few tips and tricks. We know that the table of 11 is very easy to learn because it is the repetition of the numbers 1, 2, 3 and so on.

The values of squares 1 to 100 between 30 and 50 are 6² (36) and 7² (49). Explore math program.

Prime factorization of 30 and 50 is (2 × 3 × 5) and (2 × 5 × 5) respectively. As visible, 30 and 50 have common prime factors. Hence, the GCF of 30 and 50 is 2 × 5 = 10. GCF of 30 and 50 by Long Division. GCF of 30 and 50 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.

Example 2: Find the mean percentage of the work completed for a project in a country where the assumed mean is 50, the class size is 20, frequency is 100, and the product of the frequency and deviation is - 42. Solve this by using the step-deviation method.
