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.
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. In this case, the question requires the GCF of just one number: which is LCM(56, 84).
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
LCM of 288 and 39 is 3744
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.
It is: 144

That depends on the value of A.
It is: 126
