Because 1 and 2 are the only numbers you can multiply that will result in a product of 2.
1 has only 1 factor (1) 2 has only 2 factors (1 and 2) 3 has only 2 factors (1 and 3) 4 has only 3 factors (1, 2, and 4) 6 has 4 factors (1, 2, 3, and 6) 8 has 4 factors (1, 2, 4, and 8)
The only factors of 2 are 1 and 2. The factors of a prime number are 1 and the number itself.
2 is a prime so its only factors are 1 and itself. The only prime factor of 2 is 2.The prime numbers of two are 1 and two.1*2=22*1=2
Factors of 2 are: 1, 2Factors of 14 are: 1, 2, 7, 14The only factors they have in common are 1 and 2
Numbers having only 2 factors are prime numbers. Their only factors are 1 and themselves. Prime numbers. The only two factors should be 1 and itself.
2 is a prime so its only factors are 1 and itself.
All prime numbers have only 2 factors. A prime number has 1 and itself as its only factors.
1 and 2 are the only common factors.
2, 3 and 5 are prime, their only factors are one and themselves. The factors of 4 are 1, 2 and 4. If you're asking what factors they have in common, the only one is 1.
The factors of 6 are 1, 2, 3, and 6 .The factors of 8 are 1, 2, 4, and 8 .The common factors of 6 and 8 (numbers that are factors of both) are 1 and 2 .
17 If the number has only two factors, it must be a prime number. The only factors of 17 are 1 and 17. The difference between 1 and 17 is 16.
The only number that is a factor of all the numbers from 1 to 100 is the number 1. The only factor of 1 is 1. The factors of 2 are 1 and 2. The factors of 3 are 1 and 3. The factors of 4 are 1, 2, and 4. The factors of 5 are 1 and 5. The factors of 6 are 1, 2, 3, and 6. The factors of 7 are 1 and 7. The factors of 8 are 1, 2, 4, and 8. The factors of 9 are 1, 3, and 9. The factors of 10 are 1, 2, 5, and 10. The only common factor of these ten numbers is 1. Since all numbers are divisible by 1, the greatest common factor is 1.
