What is the LCM of 7 21 35?
The LCM of 7 21 35 is 105
LCM of 30 and 21?
210. 30 = 2 x 3 x 5 21 = 3 x 7 lcm = 2 x 3 x 5 x 7 = 210
What is 2 thirds plus 5 sevenths?
2/3 + 5/7 (the common denominator is 21, the LCM of 3 and 7) = 2*7/3*7 + 5*3/7*3 = 14/21 + 15/21 = (14 + 15)/21 = 29/21 = (21 + 8)/21 = 21/21 + 8/21 = 1 + 8/21 = 1 8/21
What is the LCM of 21 and 35 and 42?
Note that 21 x 2 = 42, so we really only need to look at 35 and 42. So 7 x 5 = 35, and 7 x 6 = 42. There is a common factor of 7. So we have 7 x 5 x 6 = 210 is the LCM.
What is the LCM of 5 7 21?
LCM of 5 7 21 is 105.
What is the LCM of 7 3 5 21?
105
What is the LCM of 21 and 40 how to solve it?
Prime factors of 21 are: 3 and 7 Prime factors of 40 are: 23 and 5 LCM = 23*3*5*7 = 840
What is the LCM of 21 3 and 35?
3 is a factor of 21, so ignore it. 21 factors to [3 7] 35 factors to [5 7] common factor [7] LCM = 21 * 35 / 7 = 105 ■
What two numbers have 105 as their LCM?
The two numbers that have 105 as their least common multiple (LCM) are 15 and 7. This is because the LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, 15 and 7 are both factors of 105, and no smaller number can be a multiple of both 15 and 7.
What is the LCM of 15 and 21 using prime factorization?
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
What is the LCM of 7 21 and 14?
The LCM is 42
What is the LCM of 7 12 and 21?
The LCM is 84.
How can you use prime factorization to find the LCM of 15 and 21?
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
What is the LCM of 7 3 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.
What is the least common multiple of 21 and 35?
The Least Common Multiple of 35 and 21 is 105.
What is the LCM of 7 21 and 35?
Its so easy. I can answer it in 1 second. The LCM is 105 (66) (51)
