What is the sum of all positive integers less than 100 that are multiples of 13?

Now the multiples of 13 lying between 13 and 91 form an arithmetic progression with a common difference of 13. The nth term of an arithmetic progression is Tn = a + (n-1)*d. Therefore the sum of all the numbers divisible by 13 and less than 100 is 364.

What is the sum of all the multiples of 5 that are greater than 100 and less than 200?

Answer: multiples are 105, 110, 115, 120 ,125,130,135,140,145,150,155,160,165,170,175,180,185,190 and 195 and their sum is 2850.

How do you find the sum of positive integers?

What Is the Formula to Calculate the Sum of Integers Formula? The formula to calculate the sum of integers is given as, S = n(a + l)/2, where, S is sum of the consecutive integers n is number of integers, a is first term and l is last term.

Is 16 and 21 co prime number?

As visible, there are no common prime factors between 16 and 21, i.e. they are coprime. Hence, the HCF of 16 and 21 will be 1.

What are the odd multiples of 17 less than 100?

Odd multiples of 17 less than 100 are 17,51, and 85.

Are all multiples of 6 even?

We can arrange the multiples of 6 in increasing order, 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96,… so that they form a simple pattern increasing by 6 at each step. Because 6 is an even number, all its multiples are even.

What is the sum of first 100 positive integers?

The sum of the first 100 positive integers is 5,050.

What is the sum of all integers from 1 to 100?

5050
The sum of all natural numbers from 1 to 100 is 5050. The total number of natural numbers in this range is 100. So, by applying this value in the formula: S = n/2[2a + (n − 1) × d], we get S=5050.

What is the sum of all positive integers less than 100?

Sum of all such integers less than 100 would be 416 .

What is the sum of all positive integers up to 1000?

995. Therefore, the sum of all positive integers up to 1000, which are divisible by 5 and not divisible by 2 is 50000.
