To determine if a word problem is asking for the Highest Common Factor (HCF) or Lowest Common Multiple (LCM), you need to carefully analyze the relationships between the numbers involved. If the problem involves finding the largest number that divides evenly into two or more numbers, it is likely a HCF problem. On the other hand, if the problem involves finding the smallest number that is a multiple of two or more numbers, it is likely a LCM problem. Understanding the specific mathematical operations required in the word problem will help you identify whether it is testing for HCF or LCM.

What is the HCF and LCM of 42 and 84?

What is the HCF and the LCM of 144 and 192?
HCF is 48 and LCM is 576
What is the HCF and LCM of the numbers 526 and 213?
hcf: 1 lcm: 112,038
Can HCF and LCM of two numbers be 27 and 288?
No. The LCM MUST be a multiple of the HCF.
How do you know that word problem is to find HCF or LCM?
Depends on what it is asking for.
What numbers have a HCF of 3 and a LCM of 3?
Two or more numbers are needed to solve for HCF or LCM.
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.
How do you know which statement sum is for HCF and which is for LCM?
The LCM will never be less than the GCF.
Why do you find LCM and HCF?
When simplifying fractions it's useful to know what is the HCF of the numerator and denominator is. When adding or subtracting fractions with different denominators it's useful to know what the LCM of them is.
What is the LCM of 10and20 to their hcf?
LCM is 20 and the hcf is 10
What is the HCF and LCM of 70 and 72?
The HCF is: 2The LCM is: 2,520
What Is The Hcf And Lcm 120 And 180?
HCF is 60 and the LCM is 360
What is the HCF and LCM of 3 and 18?
HCF = 3... LCM = 18 !
What is the HCF and LCM of 42 and 84?
hcf = 42, lcm = 84.
What is the HCF and the LCM of 144 and 192?
HCF is 48 and LCM is 576
Why you need LCM and HCF in maths?
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
