Five is prime and a factor of both numbers.
10=2*5 Any number that doesn't have a factor of 2 or 5 is relatively prime to 10. e.g. 3, 7, 11, and 21 are all relatively prime to 10. 2, 5, 15, 16, and 20 are not relatively prime since they share a factor or 2 or 5 (or both, which means they share a factor of 10, e.g. 20).
No, 10 is not a factor of either 15 or 25. Any number for which 10 is a factor will end in 0. Both 15 and 25 have 5 as a factor, but not 10.
It is 5 because 15 is not a prime number, it must be a prime number like 5
Which number is a factor of 10 , but not a multiple of 5
Answer: 1Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 10 are 1, 2, 5, and 10.The factors of 14 are 1, 2, 7, and 14.The factors of 15 are 1, 3, 5, and 15.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
15 is a factor of 45, but it is not a prime number.
The number 1 is the only common factor of co-prime numbers, which is what makes them co-prime. 9 and 10 for example or 15 and 23.
15 is not a prime number, so it can't be a prime factor.
No, 1 is not a prime number.
10=2*5 Any number that doesn't have a factor of 2 or 5 is relatively prime to 10. e.g. 3, 7, 11, and 21 are all relatively prime to 10. 2, 5, 15, 16, and 20 are not relatively prime since they share a factor or 2 or 5 (or both, which means they share a factor of 10, e.g. 20).
No, 10 is not a factor of either 15 or 25. Any number for which 10 is a factor will end in 0. Both 15 and 25 have 5 as a factor, but not 10.
10 = 2 * 5 15 = 3 * 5 The shared prime factor is 5. Another way to find this is by finding the greatest common denominator (gcd).
15 is a number greater than 10 and a factor of 30.
1, 3, 5 are all prime factors of 15 3 and 5 only. 1 is a special number that has no factors but itself yet it is not counted as a prime number.
Since the number 29 is prime, the greatest common factor of 15 and 29 is 1.
The prime factors of 15 are 3 and 5 because 3 and 5 are prime numbers that divide evenly into 15. 1 is a factor of 15, but it is not a prime number.
It is 5 because 15 is not a prime number, it must be a prime number like 5
