Is the number 1859 a prime number?
To find out if 1859 is a prime number, use the rules of division:1859 is not an even number, so it is not divisible by 2.The digits of 1859 add up to a number that is divisible by 3, so it is not divisible by 3.The last two digits (59) is not divisible by 4, so neither is 1859.The last digit is not 5, so it is not divisible by 5.1859 is not divisible by 2 and it is not divisible by 3, so it is not divisible by 6.When you double the last digit (9 doubled is 18), and subtract that number from the rest of the number (859 - 18 = 841), if the answer is 0 or divisible by 7, the number itself is divisible by 7. If you can't readily tell if the number is divisible by 7, you can do the steps again. Starting with 841, doubling the 1 is still 1, so take 1 away from 84 to get 83. 83 is not divisible by 7, so neither is 1859.The last three digits (859) are not divisible by 8, so 1859 is not divisible by 8.If the sum of the digits is divisible by 9, the number is divisible by 9. The sum of the digits is 23, which is not divisible by 9.1859 does not end with a 0, so it is not divisible by 10.If the sum of every second digit (8 + 9) minus the sum of the other digits (1 + 5) equals 0 or is divisible by 11, the number itself is divisible by 11. 17 - 6 = 11, so 1859 is divisible by 11.Since 1859 is divisible by 11, it is a composite number (a number that has at least three factors: 1, the number itself, and at least one oher factor).
What are the steps for least common multiple?
We want to express any number as multiples of numbers under 10, and as close to 0, if possible. The number 13, for example, can't be divided any more. It is called a PRIME number. So a number like 26, which is reduced to 2 x 13, is as far as you can go. 2. A number is divisible by 2 if its right-hand digit is even. 3. A number is divisible by 3 if the sum of its digits is divisible by 3. For example, the digits of the number 6,561 add to produce the sum 18. Since 18 is divisible by 3, we know that 6,561 is divisible by 3. 4. A number is divisible by 4 if the number formed by the two right-hand digits is divisible by 4. For example, the two right-hand digits of the number 3,524 form the number 24. Since 24 is divisible by 4, we know that 3,524 is divisible by 4. 5. A number is divisible by 5 if its right-hand digit is 0 or 5. 6. A number is divisible by 6 if it is even and the sum of its digits is divisible by 3. For example, the sum of the digits of 64,236 is 21, which is divisible by 3. Since 64,236 is also an even number, we know that it is divisible by 6. 7. No short method has been found for determining whether a number is divisible by 7. 8. A number is divisible by 8 if the number formed by the three right-hand digits is divisible by 8. For example, the three right-hand digits of the number 54,272 form the number 272, which is divisible by 8. Therefore, we know that 54,272 is divisible by 8. 9. A number is divisible by 9 if the sum of its digits is divisible by 9. For example, the sum of the digits of 546,372 is 27, which is divisible by 9. Therefore we know that 546,372 is divisible by 9.
How do you use divisibility rules to find at least for factors of a number?
Take the number 3336. You know it's divisible by 1 because everything is. You know it's divisible by 2 because it's even. You know it's divisible by 3 because the digits add up to a multiple of 3 and you know it's divisible by 4 because the last two digits are divisible by 4. So you've found at least four factors: 1,2,3 and 4.
Is a number a multiple of 4 of its last two digits are divisible by 4?
Yes If a numbers last two digits (assuming that it has at least two) is a multiple of 4, the whole number is also a multiple of 4. If the last two digits are 00 (assuming in this case it has at least three digits), the number is also a multiple of 4. For example, 100 and 200 are multiples of 4.
What is the least 4-digit number that is divisible by 3?
1
Which is greater the greatest whole number with 5 digits or the least whole number with 6 digits?
The least whole number with 6 digits is greater because it has more digits than 5 digits.
What is a number that has at least 3 digits and is divisible by 8?
104 / 8 = 13 then 112 120 128 136 144 152 160 and so on ...
Which is greater the greatestwhole number with 5 digits or the least whole number with 6 digits?
The least whole number with 6 digits, since 100000 > 99999
Is 1341 a prime number?
No. Since the sum of its digits (1+3+4+1=9) is divisible by 3, the entire number (1,341) is divisible by 3. Since 1,341 has at least one factor in addition to ' 1 ' and itself, it's not a prime number.
What is the least five digit number which is exactly divisible by 41000?
I suggest you try getting different multiples of 41,000, until you find one that has five digits.
Is 699 prime?
No. Since the sum of the digits is divisible by 3, (6 + 9 + 9 = 24), the whole number is divisible by 3.Since it has at least one additional factor in addition to '1' and itself, it's not prime.
