3 times 7 is one of them
It is an odd number. It is not prime. Its factors are 1, 3, 7 and 21. It is positive.
3 is a factor of 21 and it is not a multiple of 7.
3=3*1 7=7*1 21=3*7 LCM=(3*7)=(21*1)=21
3*7 = 21 3+3+3+3+3+3+3 = 21 or 7+7+7=21

Its factors are: 1 3 7 and 21 Note that 3 and 7 are prime numbers
The factors of 21 are: 1, 3, 7, and 21. The factor pairs of 21 are (1, 21) and (3, 7).`1.3,7.21
To find the Least Common Multiple (LCM) of 7, 3, and 21, we first need to identify the prime factors of each number. The prime factors of 7 are 7, of 3 are 3, and of 21 are 3 and 7. Then, we take the highest power of each prime factor that appears in any of the numbers. In this case, the LCM of 7, 3, and 21 is 21, as it includes the highest power of both 7 and 3.
1, 3, 7, 21 are the distinct factors of 21.
