What is the HCF and LCM of the numbers 526 and 213?
hcf: 1 lcm: 112,038
How would you explain the LCM of the two numbers is their product?
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
What is the lcm of 1 and 3?
To find the LCM of two numbers, you multiply them together and divide by the HCF. In this case one of the numbers is 1 and so the HCF can only be 1. Thus all we have to do is multiply the numbers together: 1x3 = 3 And therefore the LCM of 1 and 3 is 3.
HCF and LCM of p and p plus 1?
To consecutive numbers cannot have any common prime factors. Thus the HCF of p and (p+1) will be 1. To find the LCM, you multiply two numbers together and divide by the HCF. In this case, you'd do p(p+1)/1 This simplifies to p2+p So the HCF is 1 and the LCM is p2+p
What is the greatest common factor of 50 and 77?
The GCF of 50 and 77 is: 1
Why is the LCM of 12 and 13 the same as there product but the LCM of 12 and 14 is not the same as there product?
The LCM is the product of the two numbers divided by their HCF. With 12 and 13, the HCF is 1. Therefore, the LCM will equal the product. With 12 and 14, the HCF is 2. Therefore, the LCM will be half of the product.
What is tow LCM of 7 and 3?
To find the LCM of two numbers you need to multiply them together and then divide by the HCF. In this case, the numbers are coprime and so the HCF will be 1. Therefore was just have to multiply the numbers together: 7x3 = 21 And so the LCM of 7 and 3 is 21.
What is the LCM of 18 and the HCF of 3?
LCM is Least Common Multiple of 2 or more numbers. So, LCM of 1 number i.e. 18 is not defined. Similarly, HCF is Highest Common Factor of 2 or more numbers. So, HCF of 1 number i.e. 3 is not defined.
What is the LCM of two numbers that have no common factor greater than 1?
If the HCF (Highest Common Factor) of two numbers is 1, then the two numbers are relatively prime and their LCM is the product of the two numbers.
What numbers do 14 and 4 go into evenly?
1, 2.
What is the highest commen factor of 81 77 and 42?
The HCF of the given three numbers is 1
What are three pairs of numbers that have a LCM of 30 and a HCF of 1?
30 & 1. 15 & 2. 10 & 3.
