How do you find sets of two numbers if HCF and LCM are known?
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
What is the LCM of 42 and 12?
The LCM is: 84
What is the LCM of 36 42 98?
The LCM is 1764.
What is the HCF of 75 and 18?
The GCF is 3.
How do you find LCM and HCF of fractions?
You don't. LCM and GCF (HCF) refer to whole numbers. You can find the LCM of two whole numbers that happen to be denominators, but in that case we call it the LCD. You can find the GCF of two whole numbers that happen to be the numerator and denominator of a fraction, and that will let you know whether the fraction can be simplified.You can use the GCF of the denominators to find their LCM (LCD). For example,1/18 + 1/24GCF = 6 because 18 = 6*3 and 24 = 6*4, thus LCD = 18*4 = 24*3 = 721/18 + 1/24 = (1*4)/(18*4) + (1*3)/(24*3) = 4/72 + 3/72 = 7/72.
What is the HCF and LCM of 42 and 84?
hcf = 42, lcm = 84.
What is the HCF and LCM of 3 and 18?
HCF = 3... LCM = 18 !
What is the least common multiple of 42 and 72?
LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504

What is the LCM of 21 42 18?
LCM(21, 42, 18) = 126
What is the LCM of 18 and the hcm of 3?
LCM=18=2*32 HCF(guess that is what u meant, highest common factor)=3 Possibilities: 3 and 18, 6 and 9, three or all of the numbers together. Note: 3 and 6 gives a LCM of 6 3 and 9 gives a LCM of 9 6 and 18 gives a HCF of 6 9 and 18 gives a HCF of 9 Three or four out of the numbers (3,6,9 and 18) will give you LCM of 18 and HCF of 3 as well.
