### What two numbers have a lcm of 30 and a HCF of 6?

Use GCF instead of HCF. 6 and 30 would be those numbers...

### What are the lcm of 30 and 75?

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.

### What two numbers have the LCM of 30 and a HCF of 1?

2 and 15 3 and 10 5 and 6

### Which 2 numbers have a HCF of 2 and a LCM of 30?

6 and 10 2x3=6 2x5=10 HCF=2 LCM=30

30 and 3.

### How do you work out which 2 numbers have an lcm of 30 and an HCF of 3?

In these types of problems, the numbers can also be the answer. 3 and 30 have a GCF of 3 and an LCM of 30. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 90, like 6 and 15.

### What are three pairs of numbers that have a LCM of 30 and a HCF of 1?

30 &amp; 1. 15 &amp; 2. 10 &amp; 3.

### What 2 pair of numbers whose LCM is less than the product of the 2 numbers?

Any two numbers that have a common factor greater than 1 will have a LCM less than their product, eg: LCM(10, 15) = 30 &lt; 10 x 15 = 150 (since HCF(10, 15) = 5) LCM(6, 10) = 30 &lt; 6 x 10 = 60 (since HCF(6, 10) = 2) LCM(18, 27) = 54 &lt; 18 x 27 = 486 (since HCF(18, 27) = 9)
