2 x 2 x 2 x 7 = 56
2 x 2 x 3 x 7 = 84
2 x 2 x 7 = 28, the GCF
2 x 2 x 2 x 3 x 7 = 168, the LCM
Check it.
56 x 84 = 4704
28 x 168 = 4704
It checks.
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
To find the GCF and the LCM you have to first at least try to use prime factorization. So use factor trees. Or for the LCM find th least common multiples of the number.
it is fast and easy
42 126 ^ ^ 7x6 14x9 ^ 3x2 ^ ^ 7x2 3x3 7x3x2=LCM is 42
To find the Least Common Multiple (LCM) of 26 and 8, you first need to find the prime factorization of each number. The prime factorization of 26 is 2 x 13, and the prime factorization of 8 is 2^3. Then, you take the highest power of each prime factor that appears in either factorization, which is 2^3 x 13 = 104. Therefore, the LCM of 26 and 8 is 104.
They are: 12 and 360 respectively
To answer GCF and LCM questions.
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
The LCM of the given three numbers using prime factorization is 25200
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
2 x 3 x 3 = 18 2 x 2 x 5 = 20 The GCF is 2. The LCM is 180.
Product of two numbers a and b = LCM(a,b) x GCF(a,b)...(1)Here, product of 18 and 360 = 6480Now, we shall find GCF of 18 and 360 by using the method of prime factorization.Prime factorization of 18 = 2x3x3Prime factorization of 360 = 2x2x2x3x3x5It is clear from the prime factorization that gcf = 18Now using (1) we can find LCM:LCM(18,360) = Product of 18 and 360/GCF(18,360) = 6480/18 = 360So, LCM and GCF of 18 & 360 is 360 and 18.Also, it is important to note that 360 is divisible by 18 then GCF is 18 and LCM is 360.
Prime factorization is the result of expressing a number as the product of its prime factors. It will assist you in finding the GCF and LCM of any given number set.
That depends on the value of A.
It is: 60
