The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 12 and 16 are 1, 2, and 4. Therefore, the least common factor (the smallest common factor) is 1.
The greatest common factor of the numbers 8, 16 and 32 is 8.The GCF is 8.
The least common multiple of 16 and 8 is 16. Because 16 is a multiple of 8, it is automatically the LCM of the pair. Another approach: To find the least common multiple, factor each number to its prime factors and then multiply all the factors from the first number with any factors in the second number that are not repeated from the first number. The prime factors of 8 are 2 x 2 x 2. The prime factors of 16 are 2 x 2 x 2 x 2.
The least common multiple of 4, 8, and 16 is 16.
That's contradictory. The least common factor is 1. The greatest common factor (GCF) is 8.
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 64 are 1, 2, 4, 8, 16, 32, and 64. The common factors are 1, 2, 4, 8, and 16. The least (smallest) common factor is 1. The smallest common prime factor is 2.
The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 4 and 8 is 8. (See related question "What is the greatest common factor of 4 and 8?" for this calculation.) So, the least common multiple is 4 x 8 ÷ 4 = 8. Common multiples of 4 and 8 include 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, etc. Although 16 is a common multiple, it is not the least common multiple.
I think the you are looking for the greatest common factor of 16 and 24. If you really want the least common factor, it is 1 just like with any other number. The gratest common factor would be 8.
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
The least common factor of any two (or more) whole numbers is 1. Please note that there is no useful reason to get such a least common factor. Usually you'll want the GREATEST common factor, or the LEAST COMMON MULTIPLE of two or more numbers.
The factor pairs of 8 are (8,1)(4,2) The GCF requires at least two numbers.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 12 and 16 are 1, 2, and 4. Therefore, the least common factor (the smallest common factor) is 1.
The least common factor of 346 and 8 is 1384.
The least common factor of any set of integers is 1.
The question isn't quite right. you need to have at least 2 numbers for there to be a "common" factor. a better question might be "what is he greatest common factor of 8 and 16?" if your question is supposed to be "which number has 8 as it's greatest factor?" (no common) the answer is 8 as in 8*1=8
