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
Since 21 is a factor of 84, it is automatically the GCF. Since 84 is a multiple of 21, it is automatically the LCM.
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.
triplets
It can be either or both. 36 is a factor of 72. 36 is a multiple of 9. 36 is both a factor and a multiple of 36.
If 21 is a multiple of the number, the number cannot have 90 as a factor.
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.
No, 7 is a factor of them.
The factors of 21 are 1, 3, 7, 21. The factors which are not a multiple of 7 are 1 and 3.
Any multiple of 105.
No, it's a common factor.
7
21 has 3 as a factor and is a multiple of 7, and so as 210, 105, and an infinite number of other numbers.
