What number does 5 3 7 and 9 have in common?
they are odd
What is the common multiple of 7 and 9 and 21?
21 = 7 x 3 , 9 = 3 x 3 ; for the Least Common Multiple (LCM), 21 already is a multiple of 7. 21 & 9 have a common factor of 3, so LCM = 21 x 3 = 63
What is 9 divded by 7 over 3?
It is: 9 divided by 7/3 = 27/7 or 3 and 6/7 as a mixed number
What is the least common factor of 3 7 9?
The least common factor of any set of numbers is 1.
What do 9 and 7 have in common?
They have no prime factors in common, as 9 = 3*3 and 7 is prime. Their GCF is 1. They are both positive integers you can count on your fingers.
What is the greatest common factor of 7 and 9?
Answer:The greatest common factor of 7 and 9 is 1.The common factors of 7 and 9 are only 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:The greatest common factor (gcf) of 7 and 9 is 1. This is because 7 is a prime number. Whenever one number is prime, if it is not a factor of the other number, the greatest common factor is 1.Another 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 7 are 1 and 7.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 7 is 7.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.1 because factors of 7 are 1,7 and factors of 9 are 1,9,3 and the largest factor they have in common is 1.The GCF is 1.
What is the greatest common factor of 27 and 63?
The GCF of 27 and 63 is 9.The Greatest Common Factor is the highest number that divides exactly into two or more numbers.factors of 27: 1, 3, 9, 27factors of 63: 1, 3, 7, 9, 21, 63The Greatest Common Factor of 27 and 63 is 9.9The GCF is 9.
What is the least common multiple of 7 9 and 8?
7 is a prime number, and not a factor of 8 or 9. 1, 2, 4, and 8 are factors of 8. 1, 3, and 9 are factors of 9. 7, 8, and have no common factors. So the least common multiple of 7, 8, and 9 are 7 X 8 X 9, which equals 504504
What is the least common multiple of the numbers 5 7 and 9?
Factoring each number into product of primes: 5=1 x 5 7 = 1 x 7 9 = 3 x 3, 1 x 9 The number 5 is a factor of 5 only; Include 5 in answer The number 7 is a factor of 7 only; Include 7 in answer The number 3 is a factor twice of 9; Include 3x3 in answer Therefore, LCM(5,7,9) = 3 x 3 x 5 x 7 = 315 Additional content regarding LCM may be referenced at http://www.math.info/Arithmetic/LCM
What is the least common multiple of 3 5 7 and 9?
3, 5, 7, 9 => 5x7x9 = 315
Greatest common factor of 27 and 63?
Factors of 27: 1, 3, 9, 27 Factors of 63: 1, 3, 7, 9, 21, 63 So the greatest (biggest) common (same) factor (a number that can divide it evenly) is 9.
What is the least common multiples of 7 and 9?
The lowest common multiple of 7 and 9 is 63.Here's how to work it out:Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...Multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...To find the lowest common multiple you look and find the smallest number that is a multiple of both numbers (in your case 7 and 9). So, in this case the lowest multiple they both have in common is 63.637963The Least Common Multiple (LCM) for 7 9 is 63.
What is the least common denominator of 9 and 3?
9 because both 9 and 3 go into the number
What is a number with 9 factors and 3 7 and 9 also?
441
What are the common factor of 42 and 63?
A factor is a divisor - a number that will evenly divide into another number. 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The common factors are 1, 3, 7, and 21.
What is the least common factor of 9 and 21?
Answer: 1 The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3; the least (smallest) common factor is 1.
Does the numbers 1 3 5 7 and 9 have a common multiple?
No :)
