Oh, what a happy little question! The LCM, or Least Common Multiple, of 7 and 21 is 21. You see, when we look at the multiples of 7 (7, 14, 21, 28...) and 21 (21, 42, 63...), we find that the smallest number they both share is 21. Just like painting, math can be a joyful journey of discovery!
The LCM is 105.
The LCM is 84.
The LCM is 42
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.
The LCM of 7 21 35 is 105
LCM of 5 7 21 is 105.
The LCM is 252.
The LCM is 42.
3=3*1 7=7*1 21=3*7 LCM=(3*7)=(21*1)=21
LCM(21, 7) = 21
21 is the LCM of 3 and 7
