What number is divisible by 2 3 and 5?
30 is divisible by, and is the least common multiple of, 2, 3, and 5.
How do you factorise a number?
we factorise a number by finding the common factor. example: 2x+6 = 2 is the common factor the 2 is then put outside the bracket 2x+6 = 2(x+3)
What is the LCM of 3 4 5 6 7?
Write down the factors of each number. Hence 3 = 1,3 4 = 1,2,2,4 5 = 1, 5, 6 = 1,2,3,6 7 = 1, 7 Hence 1, is common to all number. 2, is common to two numbers 3, is common to two numbers 5 is common to one number 7 is common to one number. Hence 1 x 2 x 3 x 5 x 7 = 210 the LCM.
If a number is divisible by both 2 and 3 then we can say the number is divisible by?
If a number is divisible by both 2 and 3, it is also divisible by 6. This is because 6 is the least common multiple of 2 and 3. Therefore, any number that meets the criteria of being divisible by both 2 and 3 will also be divisible by 6.
What are the common factors 2 3 4?

What is the common oxidation number of cobalt?
Cobalt is a transition metal. Its oxidation states are 2 (3).
What is the greatest common factor for 12 and 20 and 24?
The greatest common factor for 12, 20 and 24 is 4. Individually factorize each number wiht prime numbers (numbers which do not have any factors except for 1 and the number itself) such as 2,3,5,7,11, etc. Then out of all the 3 factorizations, take the common number that appears in all the 3 factors and multiply them. 12 = 2*2*3 20 = 2*2*5 24 = 2*2*2*3 So the common factors in all the 3 numbers is 2*2 = 4. This is the GCF (greatest common factor)
What is the least common number of 2 3 and 7?
Their least common multiple is 42.
What number is divisible by 2 3 and 5?
30 is divisible by, and is the least common multiple of, 2, 3, and 5.
What is the lowest number divisible by 2 3 and 4?
The least common multiple of 2, 3 and 4 is 12.
What is the common number of 18 and 30?
1, 2, 3, 6
What number does 24 and 30 have in common?
1, 2, 3 and 6
How can you find the common factor of a number?
A single number cannot have a common factor. The word "common" implies that the factor is common to two or more numbers. A systematic way of finding a common factor of two or more numbers is first to find the prime factorisation of each of the numbers. The common factors are any primes that appear in each and every on of these factorisations, as well as their products. For example, suppose you want common factors of 24, 36 and 60 12 = 2*2*2*3 18 = 2*2*3*3 30 = 2*2*3*5 The factors common to all three are 2, another 2 and 3. So the common factors are 1, 2, 3, 2*2 = 4, 2*3 = 6 and 2*2*3 = 12.
How does 3 and 5 have the least common number?
because the closest number between these 2 numbers is 15
What is the greatest common factor of 60 and 72 and 96?
The greatest common factor (GCF) of a set of numbers is the greatest factor which is common to each number in the set. The GCF of a single number, such as 967260, is the number itself.
