The question wants to know the least common multiple of 4 and 12. The way to do this is to find the prime factors of these numbers. In this case:
4=2x2
12=2x2x3
The next step is to find any common factors and discard the duplicate. Both numbers have two 2s, so we can discard 2 of these. That leaves us with 2, 2 and 3. Multiply these to give the LCF:
2x2x3=12
Thus 12 is the smallest number that has both 4 and 12 as a factor.

What is the smallest number divisible by 12345678 and 9?
To find the smallest number divisible by both 12345678 and 9, we need to find the least common multiple (LCM) of the two numbers. The LCM is the smallest number that is a multiple of both 12345678 and 9. To calculate the LCM, we first need to find the prime factors of each number. The prime factorization of 12345678 is 2 x 3 x 47 x 14593, and the prime factorization of 9 is 3^2. The LCM is then the product of the highest power of each prime factor, which is 2 x 3^2 x 47 x 14593 = 12345678. Therefore, the smallest number divisible by both 12345678 and 9 is 12345678.

Why is it when you reduce fractions you need to find the greatest common factor?
The greatest common factor is the largest number that is evenly divisible by both numbers, so if you divide both numerator and denominator by GCF, the numerator and denominator will be the smallest integers possible, and still be an equivalent fraction.

When the number is divided by 4 reminder is 2. The same number is divided by 7 also reminder 2 what is the smallest possible number?
To find the smallest possible number that satisfies both conditions, we need to find the least common multiple (LCM) of 4 and 7, which is 28. Adding 2 to the LCM gives us the smallest number that leaves a remainder of 2 when divided by both 4 and 7. Therefore, the smallest possible number is 30.
What is the least common denominator of 50 and 60?
To find the least common denominator, you simply find the smallest number that can divide into both 50 and 60. So 5 is the smallest number that will divide into 50 and 60. The answer is 5
What is the second smallest number that has 12345 as factors?
To find the second smallest number that has 12345 as factors, we need to consider the prime factorization of 12345, which is 3 x 5 x 823. The smallest number with 12345 as a factor is 12345 itself. The second smallest number would be obtained by multiplying 12345 by the next smallest prime number after 3 and 5, which is 7. Therefore, the second smallest number with 12345 as factors is 12345 x 7 = 86415.
What is the smallest number divisible by 7 and 8?
Oh, what a happy little question! The smallest number that is divisible by both 7 and 8 is called their least common multiple. To find it, we look for the smallest number that both 7 and 8 can divide into evenly. In this case, the smallest number that fits the bill is 56. Just like painting, math can be a beautiful masterpiece when we take our time to understand it.
What is the least common factor of 12?
To find a common factor, you need another number to have common (shared) factor with. However, with any set of numbers, the Least Common FACTOR (the smallest (positive) whole number which divides into each of the numbers without any remainder) will always be 1.
