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.
What are the common factors 2 3 4?
The common factor of 2 and 3 is: 1 The common factor of 3 and 4 is: 1 The common factors of 2 and 4 are: 1 and 2 The common factor or 2, 3 and 4 is: 1
What are the common numbers for 24 and 39 that's a 2 digget number?
The only common factors of 24 and 39 are 1 and 3.
What is the leat common number of 2 and 3?
The LCM is 6.
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)
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.
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 do 54 and 12 have in common?
1, 2, 3 and 6
What number does 24 and 30 have in common?
1, 2, 3 and 6
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.
Why is twelve the least common multiple of 2 3 and 4?
To find the least common multiple of 2, 3, and 4, factor them: 2 = 2 x 1 3 = 3 x 1 4 = 2 x 2 (Since one 2 has already been used to factor the number 2, only one 2 counts in the factors for the number 4.) The least common multiple of 2, 3, and 4 = 1 x 2 x 3 x 2 = 12.
What is the greater common factor of 60 and 72?
To get the greatest (not greater) common factor GCF, factor each number into primes: 60 = 2*2*3*5 72 = 2*2*2*3*3 Which prime factors are common to both numbers? Two 2's and one 3. GCF = 2*2*3 = 12
What number are factors of 2and 3?
The factors of 2 are 1 and 2. The factors of 3 are 1 and 3. The only common factor is 1.
What number do 48 and 18 have in common?
As factors, 1, 2, 3 and 6.
