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=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
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.
21
Because 21 is a multiple of 1, 3, 7 and 21.
