For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16. To find the factors of a number, begin with 1 and the number itself, then divide the number by 2, 3, 4, etc., taking only pairs of factors that divide the number evenly.
The numbers that 17 is divisible by are 1 and 17. You may also be interested to know that all the numbers that 17 is divisible by are also known as the factors of 17.
238 is an even number, thus 238 is divisible by 2. Last Digit Method: If the last digit in 238 is 0, 2, 4, 6, or 8, then 238 is divisible by 2.
A number is divisible by 7 if it has a remainder of zero when divided by 7. Examples of numbers which are divisible by 7 are 28, 42, 56, 63, and 98. Divisibility by 7 can be checked by using long division, although this process can be quite time-consuming.
16 divided by 3 is 5 with a remainder of 1 ( 16 / 3 = 5 R. 1). The remainder can also be written as a fraction by using the remainder as the numerator
Before you continue, note that in the problem 16 divided by 4, the numbers are defined as follows: 16 = dividend. 4 = divisor. Start by setting it up with the divisor 4 on the left side and the dividend 16 on the right side like this: The divisor ( 4 ) goes into the first digit of the dividend (1), 0 time(s).
A: No, the number 17 is not a perfect square.
Yes, 17 is a prime number because it only has two factors, 1 and 17. No, 51 is NOT a prime number because it has more than two factors. 51 is a composite number and can be factored by any of the following numbers: 1, 3, 17, 51.
17 is a prime number from 1-100. 17 has two factors, 1 and 17. It is said to be the number with the most syllables in a range of 13-19, thanks to seven, which has two syllables. It is the seventh prime number, and the seventh prime number from 1-100.
238 is not a perfect square.
660 is divisible by 10 if 660 divided by 10 results in a whole number with no remainder. Therefore, 660 is divisible by 10. FYI: 660 divided by 10 is 66.
If the ones digit in 470 is 0, then 470 is divisible by 0. Therefore, 470 is divisible by 10. FYI: 470 divided by 10 is 47.
Divisibility by 7: The absolute difference between twice the units digit and the number formed by the rest of the digits must be divisible by 7 7 7 (this process can be repeated for many times until we arrive at a sufficiently small number).
A number is divisible by 3, if the sum of its all digits is a multiple of 3 or divisibility by 3. Sum of all the digits of 54 = 5 + 4 = 9, which is divisible by 3. Hence, 54 is divisible by 3.
Consider the following numbers which are divisible by 11, using the test of divisibility by 11: (i) 154, (ii) 814, (iii) 957, (iv) 1023, (v) 1122, (vi) 1749, (vii) 53856, (viii) 592845, (ix) 5048593, (x) 98521258.
