The easiest way to find prime factors is to divide the number by an obvious factor, and then note this down and continue. For instance, 54 is even so can divide by 2 to get 27. 27 has a digit sum of 9, so can divide by 9. This means it has 3 and 3 as prime factors. Divide by 9 and we get 3. That means that the prime factors of 54 are 2, 3, 3, and 3
Do this with 72 and you get 2, 2, 2, 3, and 3.
6 is not a prime number but it is a factor of 72
54 and 72 are divisible by 2,3.
Yes.
The prime factors of 54 are: 3 * 3 * 3 * 2 * 1
As a product of its prime factors: 2*3*3*3 = 54
The GCF of 54, 72, and 81 is 9.The prime factorization of 54 is 2*3*3*3The prime factorization of 72 is 2*2*2*3*3The prime factorization of 81 is 3*3*3*3The GCF, then, is 3*3 = 9
The greatest common factor of 54 and 72 is 18.
No. 54 isn't prime.
6 is not a prime number but it is a factor of 72
Prime factor each number. Circle the factors that are in all three numbers. Multiply those factors. 27=3x3x3 54=2x3x3 72=2x2x2x3x3 3x3=9 is the GCF
54 and 72 are divisible by 2,3.
3 is a prime factor of 72 and is contained in the prime factorization.
This requires the highest common factor of 54 and 72. First split into prime factors: 54 = 2*(3^3) 72=(2^3)*(3^2) Multiply together common prime factors: 2*3*3 = 18 18 is the HCF of 54 and 72.
GCF(36, 54, 72) = 18.
9 is not prime, so it is not a prime factor of 72, great or otherwise.
To find the least common multiple (LCM) of 45, 54, and 72, we first need to find the prime factorization of each number. The prime factorization of 45 is 3^2 * 5, 54 is 2 * 3^3, and 72 is 2^3 * 3^2. Then, we take the highest power of each prime factor that appears in any of the numbers: 2^3 * 3^3 * 5 = 540. Therefore, the LCM of 45, 54, and 72 is 540.
Yes.
