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.
If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
Can two numbers have 20 as HCF and 535 as LCM?
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
The LCM of two numbers is twice their HCF?
5 and 10 lcm- 10 and hcf= 5
What numbers have a HCF of 3 and a LCM of 3?
Two or more numbers are needed to solve for HCF or LCM.
Does the HCF of any two no is always a factor of their LCM?
If two numbers are expressed as ab and cb this is easier to work out. Assume that a and c have no common prime factors. Thus, the HCF of the two numbers will be b. The LCM is the two numbers multiplied by each other, divided by the HCF. So the LCM will be abc. b is a factor of abc, and so the HCF will always be a factor of their LCM.
What do HCF and LCM stand for?
HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
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.
If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
How do you find two numbers if HCF and LCM are known?
The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.
Can two numbers have 20 as HCF and 535 as LCM?
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
Can HCF and LCM of two numbers be 27 and 288?
No. The LCM MUST be a multiple of the HCF.
Can two numbe215r have 20 as their HCF and 215 as their LCM?
No, 2 and 10 are factors of 20. The LCM of 2 and 10 is 10.
The LCM of two numbers is twice their HCF. What can you say about thetwo numbers?
The LCM of two numbers is twice their HCF. This means that the two numbers are opposite of each other in terms of their largest common factor (LCF). Additionally, because the LCF is 2, you can say that these two numbers are opposite integers.
The LCM of two numbers is twice their HCF?
5 and 10 lcm- 10 and hcf= 5
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.
