The factors of 13 are:
1, 13
The factors of 21 are:
1, 3, 7, 21
The factors of 63 are:
1, 3, 7, 9, 21, 63 because these are the positive integers that divide evenly into 63 with no remainder.
The factors of 79 are:
1, 79
It is: 273
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.
The GCF is 1.
The factor pairs of 21 are (21, 1) (7, 3) Even considering their negative counterparts, they don't add up to -13.
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.
The LCM of 12 and 21 is 84. To find the LCM, prime factor both numbers then multiply each factor the most times it was used in either number.12=2x2x321=3x7lcm=2x2x3x7=84The Least Common Multiple (LCM) for 12 21 is 84.
No, 7 is a factor of them.
13 is a factor of 273. The number you multiply 13 by to get 273 is 21.
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.
The least common multiple of the numbers 13, 21 and 14 is 546.
The list would be endless because there is an infinite number of common multiples for 21 and 13. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the leastor lowest common multiple (LCM) of 21 and 13 is 273.
It is: 273
No, it's a common factor.
