If they have at least one 2 and one 5, they must be multiples of both 2 and 5 ie multiples of 10. So they are 10, 20, 30, 40, 50, 60, 70, 80 and 90.

Find the prime factorization of the numbers 33?

The prime factorization of the number 33 is: 3 x 11


Least common multiple of 168 and 378?

To find the least common multiple (LCM) of two numbers, you first need to find the prime factorization of each number. The prime factorization of 168 is 2^3 * 3 * 7 and the prime factorization of 378 is 2 * 3^3 * 7. To find the LCM, you take the highest power of each prime factor that appears in either number: 2^3 * 3^3 * 7 = 1512. Therefore, the least common multiple of 168 and 378 is 1512.


What is the greatest common factor of 1820 and 637?

Writing down all the factors of both numbers requires too much time so it is not a good idea to find solution by writing each factor of both numbers. Method of prime factorization is one of the good methods to find GCF. Prime factorization is like breaking a number into other numbers, prime numbers, and this factorization is unique. Prime factorization is like a blueprint for numbers. Prime factorization of 1820 = 22 x 5 x 7 x 13 Prime factorization of 637 = 7 x 7 x 13 7, 13 and 7x13 are common in the prime factorization of both numbers, but 7x13 is the greatest among these numbers. So, 7x13 = 91 is the GCF of 1820 and 637.


What is the least common multiple of 23 and 92?

The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. To find the LCM of 23 and 92, we first need to find the prime factorization of each number. The prime factorization of 23 is 23, as it is a prime number. The prime factorization of 92 is 2^2 * 23. To find the LCM, we take the highest power of each prime factor that appears in either number, so the LCM of 23 and 92 is 2^2 * 23 = 92.


What is the use of prime factorization?

Prime factorization helps to find the greatest common factor and the least common multiple which, in turn, help in the adding, subtracting and reducing of fractions.
