ANSWER: 61 is a prime number but 51 is a composite number.61 is a prime number because the factors of 61 are 1 and itself (61).51 is a composite number because the factors of 51 other 1 and itself (51) are 3 and 17.
61 has only two factors, 1 and 61, which means that it is a prime number. There are no other integers that are factors of 61. (A composite number can be divided by numbers besides 1 and itself.)
The number 61 is a prime number as it can only be divided by itself and 1.61 is a prime number. It has no factors other than 1 and itself.Yes, 61 is a prime number because its only multiples are 1 and 61.
61 is a prime number. The only two factors of a prime number are 1 and itself.The two factors of 61 are 1 and 61. There are only two factors of a prime number.The only factor pair of 61 is 1 x 61. There is only one factor pair of a prime number.The proper factors of 61 are only 1 or,if the definition you are using excludes 1, there are none.The only prime factor of 61 is 61. There is only one prime factor of a prime number - itself.The distinct prime factor (listing each prime factor only once) of 61 is also 61.The prime factorization of 61 is 61. In some cases, to emphasize that it is prime, you might write the prime factorization as 1 x 61.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
Yes 61 is an integer and it also is a prime number because it has only two factors which are itself and one
