Every positive integer greater than 1.
The number is ' 2 '. Its factors are 1 and 2.
12
2 (1 and 2)
Well, isn't that a happy little question! To find the least number that has 2, 3, and 4 as factors, we need to look for the smallest number that is divisible by all three. We can achieve this by finding the least common multiple of 2, 3, and 4, which is 12. So, the number you're looking for is 12. Happy calculating!
It has at least 2 factors: 7 and 603.
64 is the least number having exactly 7 factors: 1, 2, 4, 8, 16, 32, and 64.
Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
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.
1, 2, 3 and 4
The expression 2x3x4x5 can be simplified to 120. The number 120 has the least number of factors because it is a product of consecutive prime numbers (2, 3, and 5). When a number is a product of distinct prime numbers, it will have fewer factors compared to numbers with repeated prime factors. In this case, 120 only has 16 factors, making it the least among numbers with the same number of prime factors.
Every number has at least two factors . . . itself, and the number ' 1 ' .If those are the only factors it has, and no others, then it's a prime number.
2 factors, but a prime number has only two factors (itself and one). Note that 1 is not considered to be a prime number.
