How many integers from 1 to 100 are divisible by 2 or 3 but not both?
therefore there are 16 numbers between 1 and 100 divisible by 2 and 3.
How many numbers from 1 to 900 are there which are neither divisible by 2 3 nor 5?
Therefore, 266 numbers are there which are NOT divisible by 2,3 & 5. Correct option is (B).
How many numbers between 1 and 1200 both included are not divisible by any of the numbers 2 3 and 5?
There are 40 sets of 30 numbers 1 to 1200 (1-30, 31-60, 61-90…….). Step-by-step explanation: From this l conclude that in each set there are 8 numbers that are not multiples of 2,3 or 5, So there are 8×40=320 numbers altogether that are not multiples of 2,3 or 5.
What number is divisible by 2*3*5*7?
As the phrasing of the question goes, you require numbers between 1 and 1000, divisible by 2, 3, 5, AND 7, which means divisible by 2*3*5*7=210. Hence your answer is 4. (210, 420, 630, and 840)
How many natural numbers less than 1000 are divisible by 2/5?
natural numbers divisible by 2 and 5 = 1000 / (2 ∗ 5) = 100 natural numbers divisble by 3 and 5 = 1000 / (3 ∗ 5) = 66 natural numbers divisble by 2, 3 or 5 = 1000 / (2 ∗ 3 ∗ 5) = 33 + 1 (if we include 0) Natural number less than 1000 divisible by 2, 3 or 5 500 + 333 + 200 − (166 + 100 + 66) + 34 = 735
What is the largest number divisible by 3 (999)?
The number of integers divisible by 3 less or equal to 1000 is the largest number divisible by 3 (999) divided by 3. If we add the numbers together we get the number of integers divisible by 3 or 5. However ee note that we counted the numbers divisible by both 3 and 5 twice.
How many $240$ numbers are not divisible by $210$?
The totientof $210$ – the number of values between $1$ and $210$ that are relatively prime to $210$ – is $(2-1)(3-1)(5-1)(7-1)=48$. Using this, we can say that there are $48\\cdot5=240$ numbers not divisible by these four numbers up to $1050$.
