What is the smallest number that has exactly 1 factor?
1 has one factor 1
What is 1 called if not a prime number?
It is called a "unit". Note: by definition, 1 can not be prime because all prime numbers are divisible by exactly 1 AND itself, with the AND inferring that there is a second factor. therefore all prime numbers have exactly 2 factors, 1 AND itself. 1 is the multiplicative identity
What are greatest common factor of the numbers 34 and 38?
The greatest common factor is the highest number that divides exactly into two or more numbers. 34: 1, 2, 17, 34 38: 1, 2, 19, 38 The greatest common factor for 34 and 38 is 2.
Greatest common factor of 14 and 15?
The greatest (or highest) common factor is the highest number that divides exactly into two or more numbers. The greatest common factor of 14 and 15 is 1
Greatest common factor of 10 and 11?
The Greatest Common Factor is the highest number that divides exactly into two or more numbers. 10: 1, 2, 5, 10 11: 1, 11 The Greatest Common Factor of 10 and 11 is 1.
Which composite numbers less than 10 have exactly one factor that is prime?
1
What is the lowest common factor of 5 7 and 10?
The Lowest Common Factor of ANY set of numbers is 1 - it is the smallest positive integer that divides exactly into each of the numbers which will always be 1. Perhaps you meant either: HIGHEST Common Factor - the greatest integer which divides exactly into each of the numbers; HCF(5, 7, 10) = 1 However, I suspect that you really wanted the Lowest Common MULTIPLE which is the smallest number into which all the numbers divide exactly; LCM(5, 7, 10) = 70.
Find all the prime numbers between 1 and 10?
Prime numbers are any numbers with 2factors exactly, 1, and themselves. Those are: 2,3,5, and 7. 1 is not considered prime because it has only 1 factor.
Is a factor a number that is divides exactly into two or more numbers?
That's a common factor.
What is the smallest number that has exactly 1 factor?
1 has one factor 1
1 is not a prime number because it has only one factor. explain?
I think you already did. Prime numbers have exactly two factors. 1 is not a prime number because it has only one factor.

The greatest (or highest) common factor is the highest number that divides exactly into two or more numbers. The greatest common factor of 14 and 15 is 1
Greatest common factor of 10 and 11?
The Greatest Common Factor is the highest number that divides exactly into two or more numbers. 10: 1, 2, 5, 10 11: 1, 11 The Greatest Common Factor of 10 and 11 is 1.
Which are the prime numbers with 1 as the common factor?
All prime numbers have a common factor of 1.
When is 1 the greatest common factor of 2 numbers?
1 is a factor of every whole number, and the gcf of two numbers can be 1 if there is no larger factor common to both numbers.
