To find the Least Common Multiple (LCM) of two numbers, we need to first find the prime factorization of each number. For 2x2x3, the prime factors are 2 and 3. For 3x5x5, the prime factors are 3 and 5. The LCM is the product of all prime factors raised to their highest powers, so the LCM of 2x2x3 and 3x5x5 is 2x2x3x5x5 = 300.
15=3x5 75=3x5x5 LCM= 3x5x5=75
LCM = 2x2x3x5x5 = 300 since 12 = 2x2x3 25 = 5x5 10 = 2x5
60 10 = 2x5 12 = 2x2x3 15 = 3x5 Thus LCM is 2x2x3x5 = 60
2x2x3=12 so therefore 12=2x2x3 2x2=4x3=12
12 4 has factors 2, 2 6 has factors 2, 3 The LCM would therefore be 2x2x3
3x5x5
To find the LCM of two numbers, you first split them into their prime factors: 30 = 2x3x5 75 = 3x5x5 Next you need to work out the HCF. Here, the HCF will be 3x5 = 15. Finally, you multiply the numbers together and divide by the HCF. 30x75/15 = 150. Therefore the LCM of 30 and 75 is 150.
No, 2x2x3 is not a prime factor. The prime factors of a number are the prime numbers that multiply together to give that number. In this case, 2x2x3 simplifies to 12, which can be further broken down into 2x2x3. The prime factors of 12 are 2 and 3.
I factor each and then use each prime factor the most it was used in either number. 40=2x2x2x5 12=2x2x3 LCM=2x2x2x3x5=120 You can also write out the multiples of each until you have one that is in both lists. 12,24,36,48,60,72,84,96,108,120 40,80,120
yes its 3x5x5
The LCM of 12, 15, and 45 is 180. The 15 can be ignored since it is already a factor of 45, next you break down the remaining numbers into their prime factors. 12= 2x2x3 45=3x3x5 You can eliminate 1 of the 3's since it is already a common actor between them So then 2x2x3x3x5=180
To find the HCF you first have to write the numbers as their prime factors: 36 = 2x2x3x3 75 = 3x5x5 The next step is to identify any common prime factors. In this case both numbers have 3 as a prime factor. Thus the HCF is 3. To find the LCM you need to multiply the numbers together and divide by the HCF. 36x75/3 = 900 Thus the LCM of 36 and 75 is 900.
