What is the LCM of 240 and 900?
240 = 2 x 2 x 2 x 2 x 3 x 5 900 = 2 x 2 x 3 x 3 x 5 x 5 Max is four 2's, two 3's and two 5's So LCM is 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5 = 3600
What is the least common multibie of 12 and 16?
The least common multiple (LCM) has enough factors from each number that you can divide the LCM by the number and get a whole number as a result (no remainder) 12 = 2 x 2 x 3 16 = 2 x 2 x 2 x 2 factor down to prime numbers (2, 3, 5, 7, 11, etc) to see relationships better. in other words, divide the factors until you can't any more without getting a remainder 12 = two of 2 and one 3 16 = four of 2 16 has more 2's than 12, so the LCM needs to have the number of 2's that 16 has. 12 has more 3's than 16, so the LCM needs to have the number of 3's that 12 has. LCM = 2 x 2 x 2 x 2 x 3 = 48 This might be more complicated than other methods, but this is the one that makes the most sense to me.
How do you make 77 with four 4's?
If you know what a factorial is, it would be (4!-.4)/.4+4! 4!=3*2*1 5!=4*3*2*1 99!=98*97*96*........*3*2*1
How many '1's in the following sequence are followed immediately by a '2' that is not immediately followed by '3' 1 2 1 3 4 5 1 2 3 5 2 1 2 6 1 4 5 1 1 2 4 1 2 3 2 1 7 5 2 1 2 5?
there are 4 .
What is the next number in this series 1 2 3 4 5 6 2 4 6 8 6 9?
First, it is going by ones: 1 2 3 4 5 6. Next it goes by 2's. 2 4 6 8. Finally it goes by 's. 6 9, next would be 12, 15.
What is the lowest common multiple of 4 and12and14?
4=2*2 12=2*2*3 14=2*7 4 goes into 12, so the lcm of 4,12, and 14 is equal to the lcm of 12 and 14 12=2*2*3 14=2*7 We can cancel the 2's and just have 2*2*3*7=84 84.
What is the LCM of 189 and 75?
4725.189 = 3*63 = 3*3*21 = 3*3*3*7.75 = 3*25 = 3*5*5.The LCM needs 3 3's, 2 5's and a 7. ... (Leave out the 3 from 75 since there are already 3's in 189.)LCM = 3*3*3*5*5*7 = 27*25*7 = 675*7 = 4725.
What is the LCM 15 6 and 25?
15 = 3 x 5 6 = 2 x 3 25 = 5 x 5 Therefore, the LCM is the product of a 2, a 3, and two 5's. 2 x 3 x 5 x 5 = 150
What is the least common multiple of 4 8 and 56?
The LCM of 4, 8, and 56 is 6. Since 4 and 8 are factors of 56, 56 is the LCM of the set. The answer can be found by dividing the 3 numbers into their prime factors, in this case 4=2x2, 8=2x2x2, and 56=7x2x2x2. The lowest common multiple is the smallest number which has all of these prime factors in. That means it has to have two 2's in (from 4) three 2's in (from 8) and three 2's and a 7 from 56. In this case, all of the prime factors of 4 can be found in 8, and all of the prime factors of 8 are in 56, so the LCM (lowest common multiple) of these 3 is 56.
What is the LCM of 210 and 450?
Start by factoring both numbers into primes: 210 = 2*3*5*7 450= 2*3*3*5*5 What's the shortest list that includes all the factors of both numbers? One 2, two 3's, two 5's, one 7 That's the recipe for lcm in this problem. lcm = 2*3*3*5*5*7 = 3150
What is the LCM of 240 and 900?
240 = 2 x 2 x 2 x 2 x 3 x 5 900 = 2 x 2 x 3 x 3 x 5 x 5 Max is four 2's, two 3's and two 5's So LCM is 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5 = 3600
What is the least common multiple of 4 and 15?
The LCM of 4 and 15 is 60.The least common multiple is the smallest number that is multiple of two or more numbers.Multiples of 4: 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60Multiples of 15: 15, 30, 45, 60The LCM of 4 and 15 is 60.The LCM must include the highest amount of each prime factor in both numbers. The highest power of 2's is 2, of 3's is 1 and of 5's is 1.So the LCM = 2 x 2 x 3 x 5 = 6060 15x1=15 15x2=30 15x3=45 15x4=60
What is the lowest common multiple for the numbers 2 and 4?
The answer is 4 because it s the smallest number that both 2 and 4 divide equally into!
What s the LCM of 4 and 9?
36
How do you work out lowest common multiple?
Reduce all numbers to prime factors and combine (most of each prime) For example, LCM of 30 and 24 30 is 2 x 3 x 5 24 is 2 x 2 x 2 x 3 The most 2's we have is 3 (in 24) The most 3's we have is 1 The most 5's we have is 1 So LCM is 2 x 2 x 2 x 3 x 5 = 120
Is 2 3's bigger than 4 7's?
2/3 = 14/21 4/7 = 12/21 So 2/3 IS bigger.
What s the LCM of 4 and 7 and 20?
It is: 140
