2 x 2 x 3 = 12
3 x 3 x 3 = 27
The GCF is 3.
The LCM is 2 x 2 x 3 x 3 x 3, or 108
2 x 3 x 3 = 18 2 x 2 x 5 = 20 The GCF is 2. The LCM is 180.
5 5 x 7 = 35 The LCM is 35.
Least Common Multiple (LCM) for 8 42 is 168.
The prime factorization of 10 is 2 x 5. You need another number to find a GCF or LCM.
The LCM of 25 and 30 is: 150The prime factorization of 25 = 5x5The prime factorization of 30 = 2x3x5GCF = 5But, what is the use of calculating GCF here?Answer: If we divide the product of 25 and 30 by GCF then the result is LCM.Product of 25 & 30 = 25x30 = 750So, LCM = 750/5 =150Least Common Multiple (LCM) for 25 30 is 150
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
