No, 7 is a factor of them.
The least common multiple of the numbers 21, 14 and 7 is 42.
There are no first 5 multiple. Multiple is singular.
The least common multiple of 7, 14, 21 and 36 is: 252
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
It's 126. -- the 6th multiple of 21 -- the 9th multiple of 14 -- the 14th multiple of 9
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.
Yes. 0, 7, 14, 21, 28
7, 14 , 21 , 28 , 35
42
42
It is: 42
The highest multiple of both 14 and 21 is their least common multiple (LCM). To find the LCM, we first determine the prime factorization of both numbers: 14 is (2 \times 7) and 21 is (3 \times 7). The LCM is calculated as (2^1 \times 3^1 \times 7^1 = 42). Therefore, the highest multiple of 14 and 21 is 42.
