What is the hcf and LCM of 14 and 30?
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
H CF and LCM of 12 and 30?
To find HCF & LCM of two or more numbers. Divide by prime numbers. We note in this case, 12, & 30 are both even numbers, so they will divide by '2'. Hence 2)12 2)6 3)3 = 1 & 2)30 3)15 5)5 = 1 First reduce both numberx to '1'. Second;ly, we note that '2' & '3' bo appear in each set of numbers. Hence 2 x 3 = 6 is the HCF Having made this multiplication we are left with a '2' in the twelve and a '5' in the thirty.. Hence 6(HCF) X 2 X 5 = 60 the LCM. Done!!!! Hope that helps!!!!

What are the two numbers with a LCM of 30 and a HCF of 3?
3 and 30
Two numbers have an LCM of 30 and an HCF of 3 What are they?
3 and 30
Which two numbers have an LCM of 30 and an HCF of 3?
3 and 30
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 2 numbers have the LCM of 30 and the HCF of 3?

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.
