All numbers divisible by both 4 and 15 are also divisible by what numbers?
a number is 6. All numbers divisible by both 4 and 15 are the multiples of 4 and 15. Since 4 and 15 have no prime factor in common (4 = 22, 15 = 3 · 5), then the least common multiple of 4 and 15 is equal to their product, namely 4 · 15 = 60. Every other multiple of 4 and 15 is divisible by 60. Thus, if 60 is divisible by a number then all the multiples of 4 and 15 are divisible by that number. Therefore, it is enough to check by which number in the given options is 60 divisible. Only 6 divides 60 and none of the other do. The answer must be (A).
Is 15 divisible by 4 different prime numbers?
No.
All numbers divisible by 4 and 15 are also divisible by what?
They are divisible by 2, 3, 4, 5, 6, 10, 12, 15, 30 and 60 at least.
How many numbers between 1 and 100 inclusive are divisible by 9 or 4?
To find the numbers between 1 and 100 inclusive that are divisible by either 9 or 4, we first determine how many numbers are divisible by 9 and how many are divisible by 4. There are 11 numbers divisible by 9 (9, 18, 27, ..., 99) and 25 numbers divisible by 4 (4, 8, 12, ..., 100). However, we must be careful not to double-count numbers divisible by both 9 and 4 (36, 72). Therefore, the total number of numbers divisible by 9 or 4 between 1 and 100 inclusive is 11 + 25 - 2 = 34.
What 3 digit number is 4 5 11 and 3 divisible by?
4 is not divisible by any 3-digit number. Nor are 5, 11 or 3. The smallest positive numbers that is divisible by 4, 5, 11 and 3 is 660.
What does 11 4 and 3 go into?
The numbers 11, 4, and 3 can go into various larger numbers depending on their least common multiple (LCM). The LCM of 11, 4, and 3 is 132. This means that 132 is the smallest positive integer that is divisible by all three numbers. Therefore, any multiple of 132 will also be divisible by 11, 4, and 3.
How many numbers between 1-60 are divisible by 4?
15 if you include 60, 14 if you don't.
Is 524 divisibility by 3?
no.. heres a trick: if you add together the numbers (5+2+4) and that answer equals a number that is divisible by 3 then the number is divisible by three 5+2+4=11 11 is not divisible by 3 therefore, 524 is not divisible by 3
What is 15 divisible by?
You can check by multiplying 15 by a couple numbers. 15 x 2 = 30 So 30 is divisible by 15. 15 x 3 = 45 15 x 4 = 60 15 x 5 = 75 45, 60, and 75 are all divisible by 15. Just increasing the number (2, 3, 4, 5, ...) to find more numbers divisible by 15.
Is it true 34215 is a divisible by 3?
