Use GCF instead of HCF. 6 and 30 would be those numbers...
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
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!!!!
There is no LCM of a single number. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM 0f 9, 15, and 25 is225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).1,2,3,5,6,10,15,30 The answer is 2 this is not even the answer forwhat the LCM for 8 and 30 ! not just 30 so who ever did this do a betterjob next time?!There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 10: 10, 20, 30 15: 15, 30 The LCM of 10 and 15 is 30.
The HCF of both numbers is 6

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.
3 and 30.
(30, 3150), (90,1050), (150, 630) and (210, 450).
2 and 15 3 and 10 5 and 6
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
30 and 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.
