LCM problems are most easily done by finding the prime factorization of the two numbers:18 = 2 * 3^220 = 2^2 * 5The LCM is the product of every prime raised to the highest exponent that appears.LCM (18, 20) = 2^2 * 3^2 * 5 = 180
the exponent is 2, expressed as twenty, squared or 20 X 20.
80 / \ 40 2 / \ 20 2 / \ 10 2 / \ 5 2 24*5
The prime factorization of 80 is: 2 x 2 x 2 x 2 x 5
The exponent that equals 20 is the logarithm base 10 of 20, denoted as log10(20). In other words, 10 raised to the power of this exponent equals 20. The approximate value of log10(20) is around 1.3010.
Prime factorization of 20 in exponential form is: 22x5
22 x 51
The prime factorization of 20 is: 2 × 2 × 5
2 x 2 x 5 = 20
Prime Factorization:20 = 2 * 2 * 530 = 2 * 3 * 5
The prime factorization of 20 is 5x2x2 or 5 x 2^2 20=2^2*5
2*2*5 = 20
20/2=10/2=5 5*2*2 equals prime factorization of 20.
The prime factorization of 12 is: 2 X 2 X 3 The prime factorization of 18 is: 2 X 3 X 3 The prime factorization of 20 is: 2 X 2 X 5
Let's do 20 first.20 can be written as 4x5. Note that 5 is prime but 4 is not. So write 4 as 2x2.The prime factorization of 20 is 2x2x5.Now for 60, we have 3x20.We can use what we just did and write the prime factorization of 60 as2x2x3x5.
The prime factorization for 12 is 2 x 2 x 3The prime factorization for 20 is 2 x 2 x 5GCF of (12,20) = 4
10 and 20 are composite numbers, not prime numbers. The prime factorization of 10 is 2 x 5. The prime factorization of 20 is 2 x 2 x 5.
