Do all numbers have more than two multiples?
Two or more nonzero numbers always have a common multiple — just multiply the numbers together. But the product of the numbers is not necessarily their lowest common multiple. For example, in the case above of 4 and 6, one common multiple is 4 × 6 = 24, but their lowest common multiple is 12.
Do bigger numbers always have more factors?
the factors of number depends on more more number of prime factors in it.
Which number is a factor of every number?
1 is the factor of every number as one divides every number exactly, without leaving any remainder behind and gives the quotient as the number itself.
Are factors always smaller?
The number of factors of a number is finite. A factor of a number is always less than or equal to the given number. Every number except 0 and 1 has at least two factors, 1 and itself.
How many numbers are there between 1 and 100 that have exactly 2 factors?
All the prime numbers between 1 and 100 like 3, 5, 11…have exactly two factors, those are 1 and itself i.e.., only two factors. All the composite numbers like 6,8, 12 …. Have more than 3 factors like for 6( 1, 2, 3, 6)…
Can a number have more than one factor?
A number will always have 1 and itself as factors. if a number has exactly one factor, it must be 1 and itself so “itself” equals 1. Thus 1 has one factor and it is the only number that has one factor. if a number has exactly two factors, those factors must be 1 and itself and there are no others.
Are there any prime numbers that have 2 factors?
A number will always have 1 and itself as factors. And thus the only numbers with 2 factors will be prime numbers. The only prime numbers below 20 are 2, 3, 5, 7, 11, 13, 17 and 19, and thus these are the only numbers below 20 that have 2 factors.
What is the meaning of factor in numbers?
The meaning of factor is a whole number that can divide a greater number evenly. Each prime number will have only two factors, i.e. 1 and number itself, whereas each composite number will have more than two factors, that include prime factors also.
Which is a composite number with more than two factors?
A composite number is a natural number or a positive integer which has more than two factors. For example, 15 has factors 1, 3, 5 and 15, hence it is a composite number. Is 2 a composite number? No, 2 is not a composite number because it has only two factors, i.e. 1 and 2. Hence, it is a prime number.
