The multiplication table for 3 produces 3,6,9,12,15,18,21,24, and 27, etc. etc.
The multiplication table for 9 produces9,18,27,36,45, etc.
So you can see that the lowest number which you can find in both tables that the numbers 6 and 9 divide into is18, so that is the LCM of those two numbers.
LCM means Lowest Common Multiple.
2 x 3 = 6
3 x 3 = 9
2 x 3 x 3 = 18, the LCM
Using the prime factors of 14 and 6, the LCM is 42 (2 x 3 x 7).
factoring 22=2*11 12=2*2*3 6=2*3 9=3*3 lcm=2*2*3*3*11=396
true 2x3=6 LCM (2,3)=6 3x5=15 LCM (3,5)=15 2x5=10 LCM (2,5)=10
6=1x2x3 7=1x7 9=1x3x3 LCM is the prime factors that were the MOST in any one number. 1x2x3x3x7=126
This is a LCM question, so factor all and find the highest power of each prime factor. 2 is prime 3 is prime 5 is prime 6 is [2 3] 7 is prime. LCM is [2] [3] [5] [7] so the answer is 210◄
Using the prime factors of 14 and 6, the LCM is 42 (2 x 3 x 7).
2 x 2 = 4 2 x 3 = 6 2 x 2 x 3 = 12, the LCM
Prime factors of 5 = 5 Prime factors of 6 = 3x2 Thus LCM = 3x2x5 =30 Simple, Year 6 stuff.
The LCM of 6 and 37 is 222. Because 37 is prime, the LCM of the pair is their product.
factoring 22=2*11 12=2*2*3 6=2*3 9=3*3 lcm=2*2*3*3*11=396
The GCF is 6. That makes the LCM 42.
If C is co-prime with 6 and with 7, then LCM(6, 7, C) = 42*C If not, the answer depends on the value of C.
The LCM of 6 and 13 is 78. Because 13 is prime, the LCM of the two numbers is their product.
To find the LCM of two numbers we first need to split the numbers into their prime factors. In this case: 6 = 2x3 275 = 5x5x11 You would then cancel any duplicate prime factors, but as there are none, we simply multiply all these prime factors together: 2x3x5x5x11 = 1,650 So the LCM of 6 and 275 is 1,650
true 2x3=6 LCM (2,3)=6 3x5=15 LCM (3,5)=15 2x5=10 LCM (2,5)=10
The GCF of 6 and 16 is 2. The LCM is the product of 6 and 16 (96) divided by the GCF (2) The LCM is 48.
6=1x2x3 7=1x7 9=1x3x3 LCM is the prime factors that were the MOST in any one number. 1x2x3x3x7=126
