Express the product factor of 18?
2x3x3=18
What is the gcf of 18 and 16 in math?
The GCF is 2. The prime factorization of 18 is 2x3x3 and the prime factorization of 16 is 2x2x2x2. They both have one 2 in common so that would be the greatest common factor.
What is the LCM of 18 20 and 30?
To find the lowest common multiple for numbers, prime factor each the use each prime number the number of times it appeared the most in each number. 18=2x3x3 20=2x2x5 30=2x3x5 lcm=2x2x3x3x5=180
How would you estimate the area of a baked cake in a circular pan?
2 X 3.14 X radius2 + 2 X radius X heigth radius is 1/2 the diameter Example: cake pan 6" diameter by 3" tall 2x3.14x32+2x3x3=74.52sq. inches
Can 12 over 18 be reduced?
Yes, 12/18 can be reduced : (divide both by 2) it turns into 6/9 then (divide both by 3) into 2/3. Reduction is the division of both numerator and denominator by the same term (one of the 'factors', integer constituents, of both numbers). For even numbers, divide both by 2 until one or both become odd, then attempt higher numerical factors (3, 5, 7, etc.). 12 = 2x2x3 and 18 = 2x3x3 / common factors are one 2 and one 3. Dividing numerator and denominator by 6 will yield the reduced value 2/3.

What is the LCM of a pair of numbers whose prime factorizations are 2x2x3x5 and 2x3x3?
The LCM of 60 and 18 is 180
What is the HCF of18 and 54?
To find this, you first have to split the numbers into their prime factors: 18 = 2x3x3 54 = 2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you: 2x3x3 = 18 Therefore the HCF of 18 and 54 is 18.
What is the GCF for 90 90 and 18?
18 = 2x3x3 so the factors of 18 are 1, 2, 3, 6, 9, 18 90 = 2x3x3x5 so the factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 The gcf of 18 and 90 is 2x3x3 = 18
What is 5 radical 18 equal?
factor the 18. 18=2x3x3. Take out the 3 because it is squared. 5x3 radical 2=15radical2
What is the LCMs of 18 and 20?
18 = 2x3x3 20 = 2x2x5 lcm = 2x2x3x3x5 = 18x10=180
What's the lcm of 18 and 24?
Factor both into primes and choose each prime the MOST it was used in either number. 18=2x3x3 24=2x2x2x3 2x2x2x3x3=72
