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.
30 is divisible by, and is the least common multiple of, 2, 3, and 5.
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)
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.
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
The only common factors of 24 and 39 are 1 and 3.
There an infinite number of common multiples of 2, 3 and 18. The least of these is 18.
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.
The LCM is 6.
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
The common oxidation states of cobalt are +2 and +3.
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)
Their least common multiple is 42.
1, 2, 3, 6
1, 2, 3 and 6
1, 2, 3 and 6
The least common multiple of 2, 3 and 4 is 12.
30 is divisible by, and is the least common multiple of, 2, 3, and 5.
