Is this true or false ' if 2 numbers are each divisible by another number then their difference is also divisible by that number'?

True, and this property is useful for finding the greatest common factor (GCF) of two (or more) large numbers.
If A > B, then GCF(A , B) = GCF(A - B, B) where A - B is smaller than A.
Repeat, each time subtracting the smaller number from the bigger.
Keep going until both numbers in the parentheses are the same: that number is the GCF of A and B.
GCF by subtraction rather than factorising or division. Unfortunately, it can be quite slow. You could speed it up by doing A - 2B or A - 3B etc rather than A - B.

When a number is divisible by another number what is it?
All numbers are divisible by 1. So, apart from the number 1, all numbers are divisible by another number. These numbers are therefore prime or composite.
What number is divisible by the most numbers?
There can be no such number. Suppose n is a number that is divisible by k numbers. Suppose p is any integer greater than 1. Then n*p is a number that is divisible by at least k+2 numbers.In this way it is always possible to find another number that is divisible by more numbers.
What is the definition for a factor in prime and composite numbers?
A number by which another is exactly divisible.
What odd number is divisible by an even number?
No odd numbers are divisible by even numbers.
What is the largest numbers can be divisible by 3 and 5?
There is no such number. If you have any such number, n, that is divisible by 3 and 5 then n + 15 is larger, and is divisible by both. And you can add another 15 to that number, and then to that, for ever more.

What is the Lcms of 5 and 15?
If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).
What is the difference between a multiple and factor and divisible?
a multiple is the number you can make by multiplying a number with another number.ex: multiple of 10= 10,20,30,40,50,60 ...a factor is a number which, when multiplied by another number, produces a given number.ex: 5 is a factor of 20, so is 4a common factor is the largest number given in the problemex: the GCF of 30 and 42 is 6this was answered by a 12 year old.
What is the definition for a factor in prime and composite numbers?
A number by which another is exactly divisible.
What is the meaning of composite in math?
Composite numbers are numbers which are divisible by another number other than 1 and the number itself. Ex 1: 15 is divisible by 1, 3, 5 and 15. So, 15 is a composite number. Ex 2: 3 is divisible by 1 and 3 only. So, such numbers which are only divisible by 1 and the number itself are known as Prime numbers.
What odd number is divisible by an even number?
No odd numbers are divisible by even numbers.
Why is162 divisible by 6?
A natural number (all numbers without decimal places) are considered to be divisible by another natural number, when the result of the division is another natural number (i.e. no rest or decimal places arising). Since 162/6 = 27 162 meets the requirements to be divisible by 6. All numbers divisible by 2 and 3 are also divisible by 6.
What is the largest numbers can be divisible by 3 and 5?
There is no such number. If you have any such number, n, that is divisible by 3 and 5 then n + 15 is larger, and is divisible by both. And you can add another 15 to that number, and then to that, for ever more.
What is 49 divisible by?
A number being divisible by another number is a different way of saying the factors of a number. Factors are numbers you can multiply together to get another number. 49: 1, 7, 49
What numbers are not divisible by 7?
There is an infinite number of numbers that are not divisible by seven!
What numbers are divisible by 511?
An infinite number of numbers are divisible by 511
