What is the greatest common multiple of 14 and 21?
The greatest common multiple of any set of integers is infinite.--------------------------------------------------------------------------------------------------------Did you perhaps mean:the greatest common FACTOR (the greatest number which divides into 14 and 21 without remainder): gcf(14, 21) = 7;the LOWEST common multiple (the smallest number which is a positive multiple of both 14 and 21): lcm(14, 21) = 42
What are the least common multiple and greatest common factor of 21 and 84?
Since 21 is a factor of 84, it is automatically the GCF. Since 84 is a multiple of 21, it is automatically the LCM.
What is the least common multiple of 8 14 21?
you would have to make a factor tree for 8, 14, and 21. 8 equals 2*2*2. 14 equals 7*2 and 21 equals 7*3. Then you have to see what is the lowest number that they have in common. 8,14,21 do not have a number in commone so there isn't a common multiple.
What is the highest common factor of 3 and 21?
triplets
What are the least common factor of 10 and 21?
The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.The smallest non-one common factor of 7 and 21 is 7.The Lowest Common Factor of any set of numbers is 1.I suspect this is not what you want. There are:Lowest Common Multiple which is the lowest (positive) whole number which is a multiple of all the numbers; LCM(7, 21) = 21 (3 × 7 = 21, 1 × 21 = 21);Highest Common Factor which is the largest (positive) whole number which divides into all the numbers without remainder, that is is a factor of all the numbers; HCF(7, 21) = 7 (7 = 1 × 7, 21 = 3 × 7).
What number is it has 90 as a factor thre number is prime 21 is the multiple of the number?
If 21 is a multiple of the number, the number cannot have 90 as a factor.
What are the greatest common factor and least common multiple of 21 and 84?
The GCF of 21 and 84 is 21, since it is a factor of 84. The LCM of 21 and 84 is 84, since it is a multiple of 21.
Is 7 a multiple of 14 and 21?
No, 7 is a factor of them.
What number is a factor of 21 but not a multiple of 7?
The factors of 21 are 1, 3, 7, 21. The factors which are not a multiple of 7 are 1 and 3.
What number has 21 and 15 as a factor?
Any multiple of 105.
Is 7 a common multiple of 14 and 21?
No, it's a common factor.
What number is a factor of 70 is a prime number and 21 is a multiple?
7
Which number is a multiple of 7 and has 3 as a factor?
21 has 3 as a factor and is a multiple of 7, and so as 210, 105, and an infinite number of other numbers.
What is the greatest common multiple of 14 and 21?
The greatest common multiple of any set of integers is infinite.--------------------------------------------------------------------------------------------------------Did you perhaps mean:the greatest common FACTOR (the greatest number which divides into 14 and 21 without remainder): gcf(14, 21) = 7;the LOWEST common multiple (the smallest number which is a positive multiple of both 14 and 21): lcm(14, 21) = 42
What are the lowest common multiple of 3 and 7?
Least Common Multiple:21 Greatest Common Factor:1
Which number is a factor of 21 but not a multiple of 7?
3 is a factor of 21 and it is not a multiple of 7.
What are the least common multiple and greatest common factor of 21 and 84?
Since 21 is a factor of 84, it is automatically the GCF. Since 84 is a multiple of 21, it is automatically the LCM.
