They are both primes so the only factor in common is 1. There are infinitely many multiples and they are members of the set defined by 6*k where k is an integer.

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 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.
How do you determine the greatest common factor of a number?
Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Select the common factors.2 x 3 = 6, the GCF
What is the greatest common divisor of 3 and 2?
There is none. A common divisor is a number which can be used to divide your quantities with , and finish up with a Whole Number with both of them . EXAMPLE Take the numbers, 6 and 15 The only number which you can divide BOTH of them with, and get a whole number as an answer, is the number 3 This number is called the Common Divisor. Let me do it for you: 6 divided by 3 equals 2. And 15 divided by 3 is 5. How do you find out what the common divisor is ? Answer. Break both the numbers into all the prime number 'factors'. E.g. Factors of 6 are 3 x 2. Factors of 15 are 3 x 5. Now you use the factors which are contained in BOTH of them. They BOTH contain only the number 3 as their COMMON factor. This number 3 is the Common Divisor. Now you can see why (your question ) 3 and 8 do not have any common divisor because the factors of 8 equal 2 x 2 x 2 and the factors of 3 is only 3. They have NOTHING in common , so they have no common divisor. MORE: The number 1 is a comon divisor or common factor, but we ignore that because everyone knows that 1 is a common factor in every number you can think of.
What is the leat common number of 2 and 3?
The LCM is 6.
How we can find the LCM OF 36 , 72 & 108?
Step 1 Find the prime factors of each number 36 = 2×2×3×3 = 2²×3² 72 = 2³×3² 108 = 2²×3³ Step 2 Find LCM L - Highest (Find the number with the highest exponent) C - Common (Find the common number EG. 2 and 3) M - Missing ( Take what ever is missing that is not common) LCM : 2³×3³ = 216 Your LCM is 216
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 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 lowest number divisible by 2 3 and 4?
The least common multiple of 2, 3 and 4 is 12.
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 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.
What is a common number that 7 3 1 2 and 11 have in common?
The only common factor of that set of numbers is 1.
