2 x 3 x 3 = 18
2 x 2 x 2 x 3 = 24
2 x 2 x 2 x 3 x 3 = 72, the LCM
72
2 x 3 x 3 = 18 2 x 2 x 5 = 20 The GCF is 2. The LCM is 180.
2 x 3 x 3 = 18 3 x 7 = 21 2 x 3 x 3 x 7 = 126, the LCM
18 = 2 * 3 * 3 = 2 * 32
The prime factorization of 18 is 2*3*3 or 2 * 3^2
2 x 3 x 3 = 18 2 x 3 x 5 = 30 2 x 3 x 3 x 5 = 90, the LCM
It is: 144
It is: 32*25 = 288
18 in pime exponents is 2*32 24 in prime exponents is 23*3 LCM: 23*32 = 72
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.
2 x 3 x 3 = 18 2 x 2 x 5 = 20 The GCF is 2. The LCM is 180.
18 = 2*32
2 x 3 x 3 = 18 2 x 11 = 22 2 x 3 x 3 x 11 = 198, the LCM
18 = 21 x 32
2 x 3 x 3 = 18 3 x 7 = 21 2 x 3 x 3 x 7 = 126, the LCM
2 x 3 x 3 = 18 3 x 3 x 5 = 45 2 x 3 x 3 x 5 = 90, the LCM
2 x 32 = 18
The greatest common factor of 12, 18, and 28 is 2.The prime factorization of 12 is 2*2*3The prime factorization of 18 is 2*3*3The prime factorization of 28 is 2*2*7So the greatest common factor of the set is 2.
